Boss Arsene Wenger is still hoping to keep the Chilean forward, 28, but fears he has already decided to leave.

And he is determined to keep him away from rivals Chelsea and Manchester City by striking a £50million deal with PSG.

Wenger is friends with PSG president Nasser Al- Khelaifi and suspects he has already held talks with Sanchez.

Arsenal’s 22-goal top-scorer is about to enter the final year of his contract and has refused to negotiate a new one.
