Ander Herrera
Ander herrera is an injury doubt for Manchester CityGetty

Manchester United manager Louis van Gaal has revealed that he has no idea if Ander Herrera will be fit to play against Manchester City in an all important derby at the Etihad stadium. A loss here will all but end United's chances of finishing in the top four and make LVG's situation at the club untenable after a disappointing season in terms of results.

Herrera trained with the team before the game against Liverpool in the second leg of the round of 16 tie of the Europa League that ended in a 1-1 draw, ending United's torrid run in Europe. However, the midfielder tweaked his groin in training and was unavailable for the fixture and is now a growing doubt for their trip to the Etihad.

"I don't know," LVG said when asked if Herrera will be fit for Sunday, as quoted by the Guardian. "Wednesday he trained with me and he was not injured."

The Red Devils have been strung with a series of injuries this season but the count is coming down and apart from long-term injuries to the likes of Luke Shaw, the other players should be back in action in the coming days. Bastian Schweinsteiger, Jesse Lingard and Ashley Young are all back in the first team mould with the German expected to make his first start in over two months against City.

United are currently four points behind City and a loss will open the gap up to seven points, with only eight games left in the season. The Red Devils are still active in the FA Cup, where they have to face West Ham in a FA Cup replay to progress into the semi-finals. A trophy after a disappointing league campaign can help salvage the Red Devils's season, who haven't won the cup in over a decade, but the situation already looks dire for the Dutchman, with Jose Mourinho having already made a gentleman's agreement with chief executive Ed Woodward to take over the next season.
