Yes, Mbappe's decision to leave PSG at the end of this season is completely clear. So, this is certainly clear enough for PSG to immediately formulate various plans to replace Mbappe in their team. In the French League, PSG will still be first even without Mbappe, but on the other hand, there are several other leagues they have to conquer, especially UCL, and Mbappe is PSG's main source of strength so far. So indeed PSG should look for a significant replacement for Mbape, whether it will be successful or not, but maybe it won't be as good as Mbappe.
If Mbappe ultimately decides to leave, Luis Enrique can prepare other players in the attack line and releasing Mbappe will not be a big problem as long as PSG is willing to buy other players for the empty front line. Holding back players who want to leave also doesn't have any effect and in fact the players become less and less enthusiastic about helping the team in every match because they no longer intend to stay. PSG have to prepare for local matches and the Champions League and they need to concentrate rather than following the issue of Mbappe's move and Luis Enrique also has to look for options if he ends up leaving.
Some rumors have been awaiting here and it has been a ho topic currently.
I read in some news that Rashford becomes one of the players that is currently rumored and identified to be the replacement of Mbappe in PSG. He is considered as the most potential candidate for the replacement. Additionally, there are also some other names like Rafael leao and also Osimhen. Well, this is becoming more interested. I really thought before Mbappe decision, I thought that he will stay again in PSG like previously. But with his very clear statement, finally, he will move.
Mbappe-PSG rumorWe may expect that Mbappen can move to Real Madrid, as what we have heard the rumuors from several years ago. But, there is also a rumor and news that Man City also meets him and interested to sign him, too. So, this will be competitive targets for Real Madrid, Man City, and maybe some other big clubs.
