The France international, who has featured in 19 consecutive games, pulled out of the warm-up prior to Thursday's 5-1 win over FC Midtjylland in the Europa League
Louis van Gaal has played down the severity of Anthony Martial's hamstring injury after the striker limped out of the warm-up prior to Manchester United's 5-1 win over FC Midtjylland.
Martial was forced to pull out of United's fixture on Thursday evening, but Van Gaal's side were able to overturn their first-leg defeat in Denmark as Marcus Rashford's double, along with an own goal from Nikolay Bodurov and strikes from Ander Herrera and Memphis Depay sealed a comfortable victory at Old Trafford.
United, who also have Wayne Rooney sidelined due to a knee problem, could be without Martial for Sunday's clash with Arsenal but Van Gaal insists the injury is not as bad as first feared.
"That is the first muscle injury and he is smart, wise to step out because it is a tight hamstring so I don't think it is very heavy," said the United boss.
