The France international midfielder has been heavily linked with a transfer to Old Trafford in recent days as Louis van Gaal looks to bolster his midfield options ahead of his second season in charge at the club.
Arsenal have also been credited with an interest in the midfielder, as the 25-year-old continues to be linked with a move away from Southampton.
However, former United shot-stopper Bosnich has claimed that a deal for Schneiderlin to move to Old Trafford is all but complete.
The Southampton star has scored 15 goals in 260 games in all competitions for the south-coast club over the past seven seasons.
Bosnich told talkSPORT: “Morgan Schneiderlin is pretty much a done deal. That will go ahead from what I’ve heard.”
Last week, speculation linking the midfielder with a transfer to United gathered pace when the club’s photographer followed the midfielder on Twitter.
