I think it's pretty clear that, compared with how we set up under Warnock earlier in the season, Harris is trying to get us to play more possession football with the fullbacks higher up the pitch. The problem is that most of our players aren't comfortable enough on the ball to play this way and the lack of pace in midfield and central defence leaves us vulnerable to the counterattack. We're hugely reliant on Tomlin to create and score goals.
