Gotta say it's a luxury for having him here, he's a player who can cover many positions, doesn't whine for not being played regularly, and does actually offer something when he's coming on; with CL competition, his presence is crucial for saving the energy of our midfielders who run all the time.
Although the time when he snapped after the ref ruled a foul from him last night in the 2nd half was a rare sight; I hope it's not a from of frustation about the heavy competition in the team.
