Manchester United v. Watford

I love Carrick.

His passing and vision are great.
 
We need to score another fast here to shut watford down and then maybe take a few players off in second half.
 
Why is it when we get injuries they are always in the same positions.
 
And why isn't Cathcart playing?

Is this like Theo Walcott at the world cup? What's he doing on our bench if he's not going to play when we lose a defender?
