Could be close, I mean West Ham play Wigan Saturday, then Fulham away before Man City at home. They could win all 3 really, Wigan are poor away (I know they beat Arsenal but the fact still remains), Fulham are focused on Europe and Man City might have already made 4th by that game and therefore rest players.
Hull play Villa on Wednesday, who need to keep winning to make Europe, then Sunderland at home, then Wigan away then Liverpool last day of the season. The thing that strikes me about Hull though is that they don't have a great deal of quality and that could cost them.
Burnley are pretty much down. They play Liverpool Saturday who are still after 4th, then they go to Birmingham (who, whilst not being that great themselves, Burnley are beyond helpess away) before facing Tottenham at home, who again might have to win to secure 4th. They need 5 points to stay up as it stands, and that's not even taking into account that West Ham will probably win games.
The two for me to go down are Hull and Burnley.
