We're not missing a player on the overlap who gets in behind opp. defence because Johnson doesn't do that. We're not missing a player that comes inside and consistently gets dispossessed. We're not missing his defensive qualities and we're certainly not short of safe, unadventurous passing in the midfield either. The only thing I'd want Johnson in for would be his experience and calmness in contrast to someone like Toure who was a Panicky Pete whenever the ball came to him.
