I don't think Harry Maguire would have been called up to the England national team if he was overrated. That's why it might be a bit harsh to say it's exaggerated. He definitely has talent and it wouldn't be right to claim otherwise. However, he is very error-prone and this causes big problems in the teams he plays for.
Manchester United was not in poor shape last season despite qualifying for UEFA Champions League competition, they've failed to meet up in the present two games played in UCL, it's a big slap on the faces of the Red Devils. However that's not our current concerns now, we points out to the Englishman. Harry Maguire messed up last season, he couldn't fit in so good in the position entrusted to him. Erik Ten Hag and United supporters were very dissapointed with his terrible performances, this made Erik Ten Hag stripped him off the team's captain band and issuing it out to the playmaker in his squad, Bruno Fernandez.
