Manchester United manager Ruben Amorim, after months of sticking to his preferred 3-4-2-1 or 3-4-3 formation, has signaled a tactical shift, experimenting with a 4-3-3 system. This change comes as a response to growing criticism and the impending departure of key players for the Africa Cup of Nations (AFCON).

Amorim's initial reluctance to deviate from his trusted back-three system was evident since his arrival at Old Trafford, overseeing 58 games utilizing the 3-4-2-1. This formation, which brought him success at Sporting Lisbon and Braga, emphasizes defensive solidity and flexible attacking patterns. The wing-backs play a crucial role, requiring dynamism in their forward runs, as well as creativity in passing and crossing. The central center-back often moves into midfield during build-up, creating a 2-3 shape, while the wider center-backs are responsible for threading balls to players between the lines. Amorim's style focuses on controlling possession with a disciplined build-up, vertical play, and versatile players.

However, the system has faced scrutiny, with critics suggesting a more traditional four-man defense would better suit the team. Amorim himself acknowledged the need for more variety in United's game, especially with the imminent absence of Amad Diallo, Bryan Mbeumo and Noussair Mazraoui to AFCON. These players have been central to United's right side, and their departure necessitates tactical adjustments.

The new 4-3-3 formation aims to address these challenges and provide a more adaptable approach. While the exact implementation remains to be seen, it is expected to offer more balance and potentially unlock the potential of players like Kobbie Mainoo, who Amorim hinted could benefit from a three-man midfield. It also allows Amad to play in his favored position on the wing, focusing on his strengths in the final third.

The shift to a 4-3-3 could see Diogo Dalot, previously deployed as a left wing-back, return to his more natural full-back position. The midfield is likely to consist of Casemiro holding, with two more advanced midfielders providing creativity and support to the attack. Upfront, the focus will be on quick transitions and exploiting spaces behind the opposition's defense.

Amorim's teams are known for their aggressive pressing strategy and quick counter-pressing in defensive transitions. They aim to win back possession quickly and exploit any space left by the opponents. The central midfielders play a crucial role in initiating quick, vertical passes to the forwards or wide players.

While the formation change signals a new phase in Manchester United's tactical identity, Amorim maintains that the most important aspect is the team's setup and ability to exploit the opponent's weaknesses. He emphasized the need to learn from past mistakes and improve the team's overall performance. The upcoming matches will reveal how effectively Amorim integrates the 4-3-3 system and whether it can bring the desired consistency and success to Manchester United.
