This was not true. Losing Mbappe will not impact PSG's playstyle considering it's only missing its good striker. Enrique continues to employ the same gameplay as when Mbappe was there but with the different striker. There's no difference here. The only difference is that PSG will be losing someone capable of scoring many goals in the French league, as he has transferred to Real Madrid.
Since when did Enrique say he would not rebuild? He has done it since he joined the club. Did you forget this was a game for eleven players? Do not attempt to centralize anything on mbappe. He's good with his choice to join madrid. The picture clearly said how big mbappe's contribution to the club this season. we may not able to see someone who was capable enough in doing it on PSG.
Goncalo? No mate, he was a flop.
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.
