Part of me is thinking we seem to largely have the measure of Chelsea this season, other part thinking this means they're well due a result against us and we generally play poorly without Silva. Even if he's not the one playing the defence splitting balls he's just integral when we're playing our best, like Kompany, Yaya, Aguero. Plus Chelsea at Wembley and in the FA Cup in particular are an odd force. Would take a scrappy as fuck 1-0 win clearing it off the line in stoppage time, whatever it takes to get to the final.
Does remind you of the incredibly fine lines when you get to this level though. Chelsea could still, despite swapping managers half way through the season and having their usual mid season mare, still go on to win 2 trophies. Spurs could even win the Europa. Rags went from treble on to only the league in a couple of weeks. We could go from playing the Rags off their own back yard (again) to definitely potless in the space of a week, whilst Chelsea would almost certainly go on to win the FA Cup and both English teams have a great shot at the Europa league. As I say, fine lines.
