It's a big one today - and now just because of the size of the two teams in action.
Liverpool are looking to avoid a third defeat in a row - yes, a third! - in the capital this evening. After losses against Crystal Palace and Galatasaray, people have been suggesting something is wrong - and today will go a long way to answering whether it is.
For Chelsea, it's been a mixed season so far. The lost last time out in the league, but did win in midweek.
I think anything that doesn't involve a red card for the Blues today will be a success.
