In other words, did what a defensive midfielder does.
What I mean is, can you name an instance of specific play where you though "well in McCarthy lad". I lost count of the amount of times I had that thought for Barry and Naismith tonight, for example.
His performance was mediocre/average/whatever, but there were specific instances which concerned me. It didn't make it a bad performance, but it worried me long term. I noticed things that Joe Allen and Jack Rodwell have made a career out of, and that's not a compliment. I'm not saying he's definitely going to be poor long term, I'm just noting the concern.
