Agree with both the previous posts. Ferdinand looked suspect again, and when he did that pirouette in the box, my heart stopped, especially since United were pretty much dominant at the time. Hopefully Evans will make the step up permanantely soon.
BB you are also right about Vidic, looked a bit suspect at times, in particular at the start, which he acknowledged, but didn't exactly fill the team with confidence, especially when Ferdinand is playing the way he is.
