Martial, 21, saw his playing time reduced last season under Jose Mourinho after his impressive debut campaign at Old Trafford.
And now that Ivan Perisic has emerged as a target for the Red Devils, some have suggested that Martial could be heading towards the exit door.

The Telegraph reported last week that Inter Milan could look to bring Martial to the San Siro on loan as part of a deal for Perisic.
But the latest odds from Betfair suggest the France winger will be staying put in Manchester this summer.
They have Martial at 1/7 to still be at Old Trafford on September 1 and it seems that he’s all but certain to stick around for Mourinho’s second season.
Paris St-Germain are the favourites to sign him should he decide to leave his current club at 11/2.
Arsenal are 10/1 to make a stunning move for Martial and Premier League rivals Liverpool are a distant 50/1 to secure his signature.
Martial has featured for United on their pre-season tour of America, playing a key role in their wins over LA Galaxy, in which he scored, and Real Salt Lake.
