Of course PSG will not let Messi go just like that, PSG will do whatever it takes to make Messi stay in Paris. But the final decision lies with Messi, he could return to Barcelona when his contract with PSG has expired.
Messi, who is one of Barcelona living legends, still loves the club that has made his name, especially now that Barcelona is being controlled by one of his closest friends. Xavi has asked Messi to help him rebuild Barcelona's strength, this request is very difficult to refuse because Messi and Xavi relationship is like family.
Well, I hope it happens to Barcelona if Messi decision is right. After all Messi is the heart of Barcelona that cannot be snatched away when he is done with PSG. Preparations against Mallorca also seem to be being prepared by Xavi. Given some vacant positions, he had to keep them more closely.
Followed by a very strong Inter, I expect Barcelona's game to be stronger. At least when Inter is against Bayern Munich the results obtained are the same as Barcelona. So for that, we can still see the possibility of dominating.
I think Barcelona will have to work hard to win against Inter. Their match will be quite enjoyable. The match will be very important for Barcelona. They will want to win at any cost. But there is no chance to think of Inter as a weak opponent. They will want at least a draw. Waiting to see the game.
