Casemiro's performance in Manchester United's recent 3-0 loss to Liverpool has led manager Erik ten Hag to drop him from the starting lineup against Southampton, opting instead for Christian Eriksen. The Brazilian, a five-time Champions League winner, has faced criticism for his declining form and was substituted at halftime during the Liverpool match after making two errors that contributed to the goals. With new signing Manuel Ugarte now in the squad, Casemiro faces increased competition for his position. Despite speculation about a potential move to Galatasaray, he remains at United and is focusing on redemption during training. Ten Hag emphasized the need for players to prove themselves in training to earn playing time, acknowledging that every player goes through highs and lows in their careers. Meanwhile, Bruno Fernandes may be a doubt for the Southampton match due to an ankle injury, which could further complicate United's lineup options.
