Honestly I think AWB is the signing of the season. Okay, his attacking output isn't perfect but he's make clear strides in that area. Otherwise he's one, if not the, best defensive player in the league. Has he made a mistake this season?
But I was still never concerned about a 2nd yellow, and I don't think there's many other players I'd say that for with the tackles he was making - not many modern players with that level of accuracy going off their feet to make tackles.
Saw a good stat yesterday; AWB has made 10+ tackles in a single match twice already this season, the last United player to make 10+ tackles in a match was Patrice Evra in 2012.
