sometimes big players like mbape and the likes of Christian Ronaldo could be a major distraction to other shining starts in the team and untill the leave the club, that's when you will notice that there are great replacements that could do literally the same thing they are doing at the attack. It's no doubt that mbape is a good attacker who does is job very well for PSG and his absence would be felt by both players and supporter but as a team, there will always be alternative and a substitute in the event that he's no longer in the team. The team will struggle somehow maybe for few matches to learn how to play without him but overall, PSG will survive and do well even without mbape.
