Manchester United have provided an update on the fitness of Alexis Sanchez.

The Chilean international suffered a knee injury during a clash against Southampton at Old Trafford on the weekend.

According to his interim boss Ole Gunnar Solskjaer, the winger will be out for between four to six weeks with a serious knee injury.

Sanchez will be hoping he can get fit before the end of the season.

The 30-year-old has endured a miserable time since joining United from Arsenal last January.

"It was a bad knee injury so it's four or six weeks, hopefully he'll recover quickly," Solskjaer said about the situation during his pre-match press conference before their Champions League clash with PSG.
