Yes, a fit Mikel starts over Romeu because of his expirience but let's not forget that the lad is just 20 years old and is an excellent prospect. If we plan on keeping him, we must give him more pitch time. As for the Barca game, I'd start both him and Mikel. We will need two holding midfielders if we are going to stop them from scoring, and with all honesty, I don't trust Essien in a game like this anymore.
