I'd settle for a point. Leeds and Burnley are looking at this and hoping we'll get turned over.
I just can't see us winning at both Leicester and Watford, and many are looking at Watford as a banker.
If we did manage a win on Sunday then its our biggest result of the season IMO - not necessarily because Leicester are all that but they are a very decent side nonetheless and it is away. To follow-up Chelsea with another win, that would be two games in which many might have had us down for a point at most.
Win here and it's absolutely crushing for Leeds and Burnley, but we still need Leeds result in particular to go our way also. It's potentially the season turning point if we win here.
