The Gunners now face competition from La Liga giants for the signature of the Southampton central midfielder, and may be unable to fight the lure from the Spanish club.
Schneiderlin has often declared his intentions to play for a top club in the Champions League, which Barca can almost guarantee next season.
If the 25-year-old does opt for a move to Spain, Arsene Wenger could instead turn to the services of top United target Pogba, who is currently playing for Juventus.
The two Premier League clubs will however have to stump up quite a large transfer fee if they are to lure the France international away from Serie A.
It is said that the Italian club are looking for bids around the £80million region, as the former United midfielder is being tipped to become the subject of another mega transfer switch in the summer.
