Messi parted ways with Barcelona at the end of last season after the club were unable to renew his contract due to their financial crisis.
The Argentine has not hit the ground running as most would have expected, having only scored one goal in 11 Ligue 1 appearances although he has bagged five goals in the Champions League.
Former Blaugrana midfielder Lobo Carrasco feels it will be very difficult for PSG to keep the seven-time Ballon d'Or winner if they fail in Europe.
"Messi will always miss the 'modus vivendi' he had in Barcelona," Carrasco told El Chiringuito.
"If he succeeds, which means winning the Champions League, he could extend his stay for another year.
"If PSG don't win the Champions League then this year is going to be a long one.
