I see what you're saying, but this team simply cannot operate without Mikel. Our worst offensive performances happen when he is absent. Not only does he has the necessary positional discipline to cover for players when they go forward, but his style enables the likes of Hazard, Mata and Oscar to bomb forward in the same way he used to cover for Essien and Lampard when they went marauding. There is a reason Mikel has been picked for every big game by seven different managers, and that is because he is the engine room of the team. His best work is off the ball, yet at the same time he is one of the focal points of the attack in the way he recycles the play with short, simple passes. With Romeu you have more a dynamic "Hollywood" type in the engine room, but it doesn't work from a defensive point. We were ridiculously exposed at times last night because of Romeu's indiscipline.
