Which PL Club in London?

Hey! I will be in London on 08/09 March and would like to watch Premier League football. I have already read that it is now very difficult to get tickets and if at all only with a membership. The following teams are playing at home that weekend: Crystal Palace (Sat), Brentford (Sat), Chelsea (Sun), Tottenham (Sun). Where do you think the chances of getting tickets are highest?
