Well, football. You have to see a lot of things, not only one player that made a wrong pass, or lost the ball. Just watch the first goal and see where Mikel was, and ask me where he was supposed to be. Just see what he was doing, and ask me what he was supposed to do. Hazard, Lampard and even Oscar tried to prevent Vidal from getting the ball or scoring the goal, while Mikel was walking and watching what was happening. Huge mistake from a DM that has a "tactical" role. The truth is: since Mikel became our mais DM, we are no longer as solid in the defense as we where. I dont tell me we were strong against Barcelona and Bayern, because in those games we defended with 11 players.
