Week after week, month after month, Rúben Amorim despatched out his Manchester United gamers in a 3-4-2-1 form. Many thought of it to be a mistake and, among the many many gripes about Amorim’s play, the sentiment “it is too defensive” was rife.
It’s a acquainted criticism with a back-three system; with three heart backs versus the extra typical two you’d discover in a again 4, it is simple to see how followers would suppose a workforce is setting as much as be extra defensive. However that is not essentially the case.
The final decade or so has been suffering from examples of how a workforce taking part in a again three could be among the many most attacking and aggressive within the sport — with one notably excessive case at present on present within the Dutch Eredivisie — and even Amorim’s United debunked that idea to an extent. Within the 20 Premier League video games he managed this season, the Pink Devils registered essentially the most pictures heading in the right direction (109) and collected the third-most xG (36.14) within the league, behind solely Arsenal (36.41) and Manchester Metropolis (38.02).
Now Amorim’s workforce had issues, let’s not faux in any other case, and we’ll circle again to that a bit later. However utilizing a again three is just not robotically a cue to sit down again and defend, it may be a daring and progressive form. Here is why.
Wing backs are attacking, aggressive, and tough to mark
A trademark function of the back-three system is the usage of wing backs, a place which occupies a singular place in soccer ways. It may be tough to categorise them as defenders, midfielders, or forwards as they successfully play all three roles concurrently in some of the advanced briefs the game has to supply.
Only a few wing backs are defensively minded. It was once a joke in scouting circles that each full again is a failed winger who has been pressured to drop deeper on the pitch, however within the age of “inverted wingers” and extensive forwards who can rating 40 targets a season, having a wing again who can bolster the assault is vastly helpful, as their defensive duties are sometimes lined by others.
Take Inter Milan’s duo of Federico Dimarco and Denzel Dumfries, for instance.
Left-sided wing again Dimarco has created essentially the most possibilities by far in Italy’s Serie A this season (76), has the very best Anticipated Assists tally (8.49) too, which signifies the standard of the alternatives he fashions, and spends extra time within the last third than he does wherever else on the pitch.

In the meantime, on the correct, Dumfries acts like a striker who has been pressured to play elsewhere; he’s continuously entering into the opponent’s field and presents an enormous menace when he arrives on the again publish.

With each wing backs pushed up so excessive, it’s normal for seven or eight of Inter’s gamers to document the vast majority of their touches within the opposing half, which might be uncommon for many different groups.

Crystal Palace wing again Daniel Muñoz performs in the same means. He has 15 aim involvements because the starting of the 2024-25 season and, as with Dumfries, he could be onerous for defenses to choose up as a result of he usually receives the ball within the area between their defensive and midfield strains. Plus, his unbelievable pace and stamina means he can run up and down the touchline relentlessly.
Sure coaches, equivalent to Antonio Conte and Simone Inzaghi, have acknowledged the inherent worth of wing backs and make the most of them when potential. However with the intention to unleash them, it’s a must to play a again three, otherwise you’ll be too uncovered in protection.

Hutchison: Carrick has made a mockery of Amorim’s Man United
ESPN’s Don Hutchison believes Michael Carrick has made a “mockery” of Ruben Amorim’s Manchester United.
Middle backs can push into midfield
Taking part in a again three does not essentially imply you are including an excessive amount of defensive personnel to your XI, nevertheless.
Some managers design their programs to permit one of many heart backs to step up and be part of the midfield whereas in possession. As long as that participant is snug on the ball, they’ll create a numerical overload in the course of the pitch (whereas there are nonetheless two heart backs masking behind them.)
Amorim has lengthy been a proponent of this technique. At Sporting CP, he requested Gonçalo Inacio to do that; whereas at Manchester United, he requested Lisandro Martínez, and later Luke Shaw, to hold out the function.

The move map above exhibits the strongest cluster of passes coming from what’s successfully a left heart midfield — and even left No. 10 — area on the pitch. A lot of the Pink Devils’ passing quantity went by way of Shaw (or Martínez) beneath Amorim, who pushed up and performed very near Bruno Fernandes and firm.
Atalanta’s Giorgio Scalvini has additionally carried out this function from proper heart again previously, Borussia Dortmund’s Nico Schlotterbeck additionally recurrently dribbles into midfield from left heart again, whereas Conte’s Premier League title-winning 2016-17 aspect at Chelsea inspired Brazil defender David Luiz to roam ahead and have an effect on play nevertheless he felt finest.
Nevertheless, the most effective instance of a middle again pushing into midfield and utterly altering a workforce’s dynamic is John Stones‘ function for Manchester Metropolis’s treble-winning aspect in 2022-23.

Simply over midway by way of that marketing campaign, Pep Guardiola found a tactical tweak that no workforce had a solution for. He fielded 4 heart backs (Stones, Rúben Dias, Manuel Akanji and Nathan Aké) within the line of defense, then requested Stones to affix Rodri in midfield when the workforce had been on the ball. That in flip pushed Ilkay Gündogan up subsequent to Kevin De Bruyne, making a 3-2-5 form.
Stones’ function was to recycle the ball excessive up, as a midfielder would, but in addition kind a barrier with Rodri to guard towards counter assaults. That allowed Guardiola to make use of 5 gamers to assault, unfold throughout the width of the pitch. A easy look at his move map (above) towards Actual Madrid in that yr’s Champions League semifinal would possibly idiot you into considering he purely performed as a middle midfielder … however he did not.

Middle backs can be part of the assault
Some heart backs even transcend the central midfield areas and attempt to have an effect on play within the last third extra instantly.
When Tottenham’s Cristian Romero performed in Serie A for Genoa and Atalanta, he recurrently steamed ahead and joined the assault. Sometimes he’d seem subsequent to the striker after a 40-yard sprint, sensing the possibility to reach undetected and trigger chaos.
As of late, you would possibly see Juventus’ Federico Gatti hammering up the pitch in the same vein — though not at all times from a again three, which provides additional danger to the transfer — after which there’s Inter heart again Alessandro Bastoni, who’s a stable defender and an important lengthy passer from the again, but in addition has license to push effectively past the midfield. Actually, the 26-year-old will recurrently overlap his wing again (Dimarco), obtain the ball and cross, or he’ll make an underlapping run and get into the opposition field himself.

Bastoni has had an astonishing 477 touches within the attacking third this season, the Nineteenth-most in Serie A; he closely contributes to the league’s finest assault, but additionally stays integral to a protection which have conceded simply 23 targets in 29 video games.
However should you suppose that is spectacular then prepare, as a result of NEC. Nijmegen take it to the intense.
NEC have a exceptional story. A storied, small membership from the Netherlands who’ve by no means gained a serious trophy, they at present sit third within the Eredivisie, above the giants of Ajax and different common European qualifiers equivalent to AZ Alkmaar and FC Twente.
And so they’ve risen so far by taking part in essentially the most reckless soccer you’ll ever see this season. NEC construct out from the again and assault in freeform trend, with heart backs steaming up the pitch to affix the ahead line, wingers ending up on the again and all the things in between. Elazar Dasa, the correct heart again, has despatched in 34 crosses this season, which is greater than some groups’ forwards round Europe.
NEC’s base formation is a 3-4-2-1, however as quickly as one participant makes a move, they transfer up the pitch and the form melts. It’s maybe the last word instance of why taking part in with three heart backs does not essentially imply you are taking part in defensively. In any case, solely champions-elect PSV Eindhoven have scored extra targets (77) than NEC’s 67, whereas they’ve solely conceded the joint-seventh-most (45), which is spectacular given they’ll depart themselves vastly open on the again every now and then.
Pushing the boundaries
In the identical means that no 4-4-2 is similar — Sean Dyche’s relegation-battling variant for Burnley, which hoofs the ball to a goal man, is night time and day to Unai Emery’s possession-based, managed model at Aston Villa — a again three system is just not essentially defensive.
The proof of that’s within the pudding: Inter are Serie A’s prime scorers with 65; Dortmund are the Bundesliga’s second-top scorers with 55; and Lens are Ligue 1’s third-top scorers with 49. All these groups play a back-three system persistently.
Conte has unleashed a again three to nice attacking impact over time with numerous golf equipment equivalent to Chelsea, Juventus and Napoli; whereas Manuel Gasperini, the creator of some great Atalanta groups which have thrilled in entrance of aim, can be back-three stalwart.
ESPN’s Ryan O’Hanlon not too long ago argued that the world — and most particularly the Premier League — wants extra again threes, as the pliability and ingenuity the form permits might be an efficient antidote to a world of man-marking, physicality and set items.
Not each back-three story is a hit, although … and that brings us again spherical to Amorim’s Manchester United.
His aspect missed loads of the alternatives in entrance of aim, because the Portuguese struggled to get the most effective out of younger striker Benjamin Sesko and stifled artistic midfielder Bruno Fernandes in a deeper function that closely restricted his influence within the last third. In the meantime, United had been defensively poor; solely six golf equipment let in additional targets than their 30, because the system was pressured on a squad which lacked the athleticism in heart midfield to tug it off. And now interim boss Michael Carrick has ditched it for a again 4, outcomes have improved.
However do not let that put you off. As a number of golf equipment, from final season’s Champions League finalists Inter to Dutch upstarts NEC are showcasing, a again three could be system that pushes the boundaries of “attacking” when deployed correctly. And is not that simply what soccer wants?
