The defeat occurred because Nottingham Forest played more optimally and Manchester United were busy building attacks but they forgot to defend. Nottingham Forest also cannot be ignored because they did beat a big team like Liverpool this season, but Manchester United's defeat should not have happened if their players could consistently maintain the defense area well because if you look at it, Manchester United's dominance is much better than Nottingham Forest.
Not only the defense line that must be highlighted more by Manchester United during the match, but Manchester United's attacks also did not all run optimally so that Manchester United could not equalize after Fernandes scored a goal in the 61st minute. And in the near future Manchester United will return to compete in the UEL with the hope of winning again so that they can get a much better position in the standings.
