I think there is a bit of confusion here with people saying "leaving Torres out is nonsense" etc etc. I think most people who have advocated such a move are really saying that IF WE MUST rotate, you'll never actually get a better chance than when you're playing the weakest team in the league.
All that said, FFS if we can't beat this lot without Torres and/or Gerrard, we might as well give over. There is a lot to be said though for the fact that in three out of the last four matches (and three out of the last three if like me you don't really rate the Carling Cup) we have kept exactly the same team, and by now we will be seeing the benefits of doing that. If Rafa keeps the guts of the team, making no more than two changes (say a full-back and Crouch for Kuyt) I would expect us to absolutely hammer these 3 or 4 nil. Given the importance of goal differnce if we ever do get to a point where we challenge, this might be the way to go, but as always we'll see.
