Considering he had not played a game before, he was not as bad as people are suggesting. Let's not kid ourselves, he will be used more and more because we have such a thin midfield. Hopefully he gets more match fit and plays better.
His positioning and calmness helped McSauce move around and go forward with more confidence. He doesn't offer anything going forward, but he does help us defensively.
Anyone expecting Garner to come in and play like prime Carrick is kidding themselves. He will not play better than Matic, he's a kid ffs.
I would play him for some matches at least till January, where hopefully we will sign someone for that position.
