Agreed, BUT, Anita was having a very good game as well, and was as likely to pop up with an assist, a goal, or even just create an opening as anyone else on the pitch. It isn't an argument about whether Anita or Cabaye should have been taken off. Both of them could have been kept on the pitch, and with a slight re-jig of the formation, we could have kept the pressure on. The point is rendered moot in this case because of the injury to Nasri IMO.
