I'm not McCarthy's biggest fan, he's quite a limited player - you can see that with his long passing. He rarely plays a forward pass or drives with the ball, and it looks like he shies away from receiving a pass sometimes.
But then I understand he's playing to Martinez's tactics. Somebody mentioned that he'll pick up wingers with the full backs, which is true, but it seems that that's the plan. The wingers are told not to track back, so the centre mids go wide and then there's nobody left to cover the middle. It's probably one of Martinez's worst tactics to be honest. Both of Watford's goals at the weekend came from having a big hole in centre midfield.
