I mean, since Lampard came in we've taken 8 points from 11 games against the 'big 6', with an aggregate score of 19-5. It seems a little bit of a stretch to call that a pattern of doing OK if i'm honest.
I'm not saying tonight is a must win game, those games are very rare and it only really applies at the very end of the season. The point is simply that at some point we have to start winning games, and we won't have too many better chances than at home under the lights against a midtable side. A point tonight isn't a disaster, but it will be disappointing. A side which has only won 2 away games since the manager took over a year ago cannot afford to be going at a point a game at home.
