Maguire was substituted at halftime of Wednesday's 4-1 win over Bournemouth in a pre-season friendly due to fatigue, as he is being carefully managed by the staff,
coach Ruben Amorim said in a press conference. "He had an issue during the holidays, during training. They were training in the holidays. He's a little bit late, so we have to be careful with him. It's just a little bit fatigue with the trainings, so we are trying to control everything and saving all the players, to give the exact minutes they need."
