Manchester United have a number of injury concerns at the moment as they prepare to face Arsenal at the Emirates Stadium in the Premier League on Saturday.
Goalkeeper David de Gea is doubtful for the match after dislocating his finger while training with Spain, while defenders Rafael da Silva, Phil Jones, Jonny Evans and Luke Shaw all could miss the match.
Summer signing Marcos Rojo is definitely going to miss the contest as will Ashley Young and Jesse Lingard, while Michael Carrick and Angel di Maria are struggling with fitness issues.
Daley Blind has been a key player for United so far this season following his summer move from Ajax, and he too is going to sit out the match against Arsenal.
The Netherlands international defensive midfielder's absence will be massive for United, and former Arsenal defender Martin Keown has underlined just why.
“Losing Daley Blind is probably his biggest loss because of his versatility and he’s Van Gaal’s brains on the pitch,” he told The Daily Mail.
“Those injuries don’t help and I’d sooner be playing at home after a break like that, so it’s nicer for Wenger to have a home game…
“It’s hard to say United are a weaker team going forward with the players they have but defensively they are certainly not strong.
The likes of Van Persie, Di Maria and Rooney are all in form but now there is a feeling that Manchester United have an achilles heel in their defence.”
Blind has been accused of lacking pace and not going gung-ho in tackles, but he has been one of the best players for United.
The 24-year-old is calm and composed on the ball, and his distribution has been good as well despite suggestions that he has often played the easy pass.
In eight Premier League appearances so far this season, Blind has scored one goal, created seven chances, has a 90% pass accuracy and a 43% shot accuracy.
