Manchester United were handed a major fitness worry after in-form forward Anthony Martial suffered a foot injury during France's 2-0 loss to England at Wembley. The striker left the field after 67 minutes and was seen leaving the stadium on crutches with a bandaged foot. This will be a major cause for concern for Louis van Gaal ahead of their lunchtime clash against Watford at Vicarage Road on Saturday.

Wayne Rooney and Dele Alli scored the goals either side of the interval to give the Three Lions the win on a night that was dominated by a show of solidarity by the two nations following the recent terror strikes in Paris.

The Red Devils are still uncertain on the extent of the injury, but will be sweating on his fitness with a crucial run of games coming up in the next few weeks in the Premier League and Champions League. France manager Didier Deschamps eased some fears when he claimed that the injury was just a knock, despite admitting that the striker was in a lot of pain following the match.

"He is in a lot of pain but it is just a knock on the top of his foot," Deschamps said following his side's 2-0 loss, as quoted on Sky Sports.

Meanwhile, United have received positive news with regards to Michael Carrick's injury, and according to The Daily Telegraph, the midfielder's injury is not as bad as first feared and he will not face a lengthy spell on the sidelines. The England international was stretchered off during the Three Lions' 2-0 loss to Spain in Alicante, but initial assessment by the Red Devils' medical staff have reportedly yielded positive results.

The former Tottenham midfielder is certainly ruled out for the 20-time English champions' clash against the Hornets on Saturday (21 November), but the report claims that the midfielder could be available for selection by the end of November or the start of December.

Marouane Fellaini and Chris Smalling also face a race to be fit for United's clash at Vicarage Road, with the former missing both of Belgium's matches during the international break, while the latter missed England's clash against France on Tuesday (17 November) with a minor knock. Luke Shaw and Antonio Valencia are also on the injured list and will be out for the long-term after undergoing surgery for a double leg fracture and foot injury respectively.
