Fellaini, 30, is set to become a free agent in the summer transfer market after rejecting several contract offers from Manchester United, and that has seen him being linked with a move to Arsenal, with other foreign clubs credited with an interest as well.
Fellaini appears to be at the phase of his career wherein turning mercenary for the likes of AC Milan, or clubs from Turkey or China (all rumoured to be interested in him) would be in his best financial interests.
Romelu Lukaku has described his "perfect" relationship with Manchester United boss Jose Mourinho.
"He needs a new start and I think, with his quality, I think he can help Unai Emery and he can help the Arsenal players in the squad".
"I think they'll see the change in the team itself in the first five games, but it will take time where he'll probably want to get rid of a few players, he'll want to bring a few more in".
Unai Emery has already started the rebuilding process for next season.
Pires also discussed the expected signing of PSG youngster Yacine Adli, saying that the starlet would be success at the club. "I know he's played as an attacking midfield, then he's been a holding midfielder". Sometimes he can score.
