Without Messi and Mbappe, PSG's attack will face some problems. Neymar is a good player but his fitness is not good. So PSG cannot rely on Neymar's performance. Luis Enrique must find alternatives to Mbappe and Messi. And it has to be done very quickly. Will Harry Kane be interested in coming to PSG? I don't think Harry Kane will come to PSG. He will want to join a better team. It is still uncertain which players Luis Enrique is looking to bring in to bolster his attack.
Actually without Mbappe is big problem for PSG but I believe with Luis Henrique can finding right replacement for position leaves by Mbappe and Lionel Messi. There are not any player important than teams and I think if Mbappe leaves PSG exactly have new replacement for his position, Victor Osimhen have linked for replacing Mbappe position if leaves PSG and I think right level quality have by Osimhen success become top scorer in Serie A last season. Indeed Osimhen, PSG have rumor for signing Harry Kane and looks many alternative for replacing Mbappe position and as PSG fans don't disappointed if can't extend contract.
