Currently, Arsenal's best hope is to be on third place in the league for this season. Meanwhile, Chelsea, aside from the top four spot in the Premier League, is still in other leagues such as the FA Cup final vs Liverpool and the semi-final second leg in the Champions League vs Barcelona.
That's why there's really no fall back plan for Arsenal for now. Expect them to be aggressive in this game, and leave some weak points in their defense, which Chelsea will surely try to exploit. And it is possible that Chelsea will play for a draw.
Possible lineup for Arsenal include Szczesny; Sagna, Koscielny, Vermaelen, Santos; Ramsey, Song, Rosicky; Walcott, Van Persie, Gervinho. For Chelsea, it would be Cech; Bosingwa, Cahill, Terry, Cole; Lampard, Essien; Ramires, Mata, Sturridge; Torres.
