Tensions are reportedly rising behind the scenes at Manchester United following their disappointing defeat to Tottenham, with senior players, including Casemiro, expressing frustration over head coach Ruben Amorim’s tactical decisions.

According to sources close to the dressing room, many players were left bewildered by Amorim’s unwavering commitment to a system that they felt clearly did not suit the squad’s strengths. Casemiro, in particular, is said to have been vocal in questioning why the team was asked to stick to an approach that lacked balance and left them exposed — especially against a dynamic side like Spurs.

While Amorim’s philosophy of structured buildup and wing-focused transitions has shown promise in moments, several players reportedly felt the coach was overconfident and rigid in his tactics. Instead of adjusting to Tottenham’s strengths and the realities of his own squad’s limitations, Amorim doubled down on a formation that left United vulnerable in midfield and open at the back.

One player reportedly told a close confidant that it felt like they “walked into the lion’s den with a blindfold on,” alluding to how poorly prepared they felt to counter Spurs’ energy and pace.

Casemiro, one of the few players with extensive experience at the highest level, was said to be especially frustrated. Known for his tactical discipline and ability to read the game, he reportedly struggled to understand the logic behind Amorim’s insistence on a high-press system when key personnel were clearly uncomfortable executing it.

While no public confrontation occurred, insiders suggest there was a noticeable shift in the mood within the squad after the match. Some players are quietly beginning to question whether Amorim is adapting too slowly to the demands of the Premier League and whether his system-first approach is costing them crucial matches.

The situation adds further pressure to Amorim’s tenure, with United’s hopes for a top-four finish hanging by a thread. For now, the board remains supportive, but with player morale dipping and results faltering, the harmony that greeted Amorim’s arrival is beginning to show signs of strain.

All eyes will be on how the coach responds — whether he adjusts his tactics to better suit his players or doubles down on the system that brought him success in Portugal. One thing is certain: the dressing room is no longer fully convinced.
