Luke Shaw has a hamstring injury and is out of action for a month.
Manchester United have spent big this summer, splashing the cash on Luke Shaw and Ander Herrera of Southampton and Athletic Bilbao respectively.
Shaw was, in a word, expensive. The England international cost United a massive £30 million - a world record for a teenager.
But the start to his United career has not been smooth. He was declared unfit by his new boss Louis van Gaal, something the player himself agreed with and last night he missed his potential Old Trafford debut against Valencia with a hamstring problem.
A hamstring problem that has now seen him ruled out of action for a month.
The 19-year-old's potential injury problem was discussed by van Gaal yesterday - with Jonny Evans and Antonio Valencia also potential absentees from Saturday's game with Swansea City:
“I think we have a lot of injuries now and we can’t forget that. Jonny Evans was injured, Shaw was injured and Valencia was injured, and they are three defenders. We have to wait and see if they can play on Saturday, but the main thing is that we have won in spite of playing our worst game.”
But now Sky Sports News have revealed he is out for a month - ruling him out of the curtain raiser v Swansea and potentially games against Sunderland, Burnley, QPR and potentially Leicester City.

Luckily for United they are said to be on the verge of signing both, or either, of Daley Blind or Marcos Rojo - who would be able replacements.
