Yes weak, we have Valencia as a RB and two CB's who I don't have a lot of faith in when they are under the pressure.
Also your point about Carrick isn't really true, he's been back few weeks now just on the bench. I was more referring to Herrera though.
We have to remember that everything is built on a solid foundation, right now we don't have that, especially when we are playing make-do RB's.
I hope I'm wrong, but for me it's not a good team on paper, only 1 player is in a bit of good form.. Fellaini, but I wouldn't of started him today.
