Chelsea and Manchester United have similar problems. Both have inconsistent performances. And Chelsea's defense is also relatively weak.
However, Chelsea's attacking players have performed much better and are stronger than Manchester united's. In 29 matches, Chelsea's players have scored 53 goals, while Manchester united's players have scored 37.
However winning the Conference league title is not difficult for Chelsea. Chelsea's opponents in the Conference League are relatively weak. So Chelsea's main target now is probably to secure fourth place in the Premier League table and qualify for the Champions League. Enzo Maresca is probably moving towards this goal.
Chelsea almost have same problems as Manchester United, but used different approach to solve it. The good thing is that it's worked. I'm sorry, I'm not discrediting Manchester United, however their rank in the table said it all.
Chelsea very close to the UCL qualification. We can also expect to see them back to the UCL. Meanwhile, Manchester United needs years to compete at the top table as they have to start everything from the scratch.
Chelsea is way better than Manchester United, yeah and the statistics are there. Exactly, as you said that their rank in the table says it all. If you ask me,the management of Chelsea is way better than that of Manchester United and I also think that Chelsea will resolve their set backs before Manchester United does. My opinion though.
