One of the key criticisms leveled at Amorim is his insistence on playing a 3-4-3 formation, which has yet to yield consistent results. Despite the team's struggles, he has been reluctant to make tactical adjustments, leading to further frustration among supporters and analysts alike. Carragher pointed out that other managers have successfully implemented their own systems at new clubs, often making an immediate impact. He cited the examples of David Moyes, Oliver Glasner, Nuno Espirito Santo, Unai Emery, and Eddie Howe, all of whom have transformed their teams in challenging situations.
"Moyes has won 15 points from a possible 24 since taking over, with only one win fewer than Amorim. United have collected just 18 points from 48 under new management. That must be a concern," he wrote.
"There are other examples of this. Oliver Glasner recently celebrated a year in charge at Crystal Palace, having taken plenty of big scalps playing the same 3-4-3 formation as Amorim. It took no time for his players to adjust to a new philosophy. Good coaches unlock the full potential of players, whatever their preferred system.
"Nuno Espirito Santo led instant improvement at Nottingham Forest to keep the club in the Premier League last season, an upward trajectory which has continued to make Champions League qualification a possibility. Unai Emery has been similarly transformative at Aston Villa, and from the moment Eddie Howe took over at Newcastle United, it felt as if the club’s annual relegation battles were over. Perhaps the most relevant point of comparison for Amorim is Mikel Arteta’s early work at Arsenal, United’s opponents on Sunday."
