The France international has fallen further down the pecking order with the re-signing of Cristiano Ronaldo and has been tipped to end his Old Trafford stint in the near future.
Martial reportedly rejected the opportunity to sign for Lyon on transfer deadline day last month, but his opportunities under Ole Gunnar Solskjaer this term are expected to be few and far between.
According to Eurosport, the former Monaco man is on the radar of Barcelona amid their attacking crisis, and United are willing to let the £40m-rated attacker leave in January for the right price.
However, the report adds that Martial's £250k-a-week salary could present a roadblock in negotiations with clubs elsewhere, but the 25-year-old will be prepared to seek pastures new if he cannot force his way into the first XI on a regular basis.
Martial boasts 78 goals and 50 assists from 263 games for the Red Devils but has only started one of his side's five matches in the 2021-22 Premier League season so far. body check tags ::
