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.
They did the wrong thing from the start, how dependent they were on Mbappe, and that's what made them feel a deep sense of loss after Mbappe said he would not renew his contract and their next season was certain to be without this player. I understand that Mbappe's abilities make them dependent on him, but actually they can already make preparations because in a team players will come and go at any time.
What I see is that they weren't ready for that, so they were confused, and it even took them a very long time to persuade Mbappe, even though in the end they were never able to convince Mbappe again to stay with them.
Now they have to forget about that and better focus on the team to be even better even without Mbappe. There is much they can do instead of regretting Mbappe's departure, because after all it has happened.
Departures of important players in football clubs is not new hence PSG shouldn't have much to worry about except they want to let the world know that they are a club without strategy. The sporting world have seen moves like these severally in the past and most of the clubs that lost these great players later went on to win important trophies, we saw how David Beckham left Manchester united for real Madrid, Thierry Henry left arsenal for Barcelona, Ashley Cole left arsenal for Chelsea, Luis Figo left Barcelona for real Madrid, christiano Ronaldo left Manchester united for real Madrid, and so many others. but what real makes a good club is the ability of the club to get a good replacement or sometime you have to strengthen your academy or youth system, and get better replacement which may not be world-class but deliver good football and help the team win Trophies, a very good example of such club with that kind of magnitude is borussia Dortmund.
