Manchester United manager Louis van Gaal expects to be without midfielder Daley Blind for some time.

The midfielder was taken off in the 20th minute of Holland’s 6-0 win over Latvia last Sunday with a knee injury.

Van Gaal said initial tests on the player’s knee proved inconclusive and he will undergo another scan the week after next to determine how long he would be out for.

The United boss said: “He is not ready to play.

“He has a brace on his knee and 10 days’ rest and then we have to make another scan and then we can say more about his injury.

“It is not so bad as the doctor thought after the match but it shall be a long story, I believe, but not six months or something like that.

Blind was one of five United players injured on international duty.

Luke Shaw felt a tight hamstring and groin while away with England and could miss tomorrow’s game at Arsenal.

Michael Carrick also suffered a groin problem on international duty, and he will be assessed before Van Gaal decides whether to include the player in the squad for the game at the Emirates.

Striker Radamel Falcao will be out for at least a fortnight because of a new injury.

Falcao has not played for United for a month because of a calf problem and he has now suffered another setback, the club confirmed yesterday afternoon.
