Chelsea have the chance to pull themselves clear quickly with a win on Saturday against Villa. If they win, Spurs can only hope to tie them on points, and with a gigantic goal difference, the Blues would realistically be guaranteed to finish ahead of the Tottenham.
That would leave Spurs and Arsenal to hash it out. The Gunners have a bit of luck, getting Wigan right after their FA Cup final. That leaves Spurs rooting for Newcastle to remain in the relegation battle on the final day when the Magpies play Arsenal.
