The title isn't going to happen unless something outstanding happens.
That being said Chelsea's two games in hand are against QPR away and United (albiet at home). It's not unthinkable that they could end up dropping points in both games, leaving us potentially 5 points behind and still to play them at home. I'm certainly not going to say we can win the title, because it isn't in our hands, but all we need is two results to go our way and suddenly it's not so crazy.
Also, if we're going to challenge next year we REALLY need a new keeper, one who can pull off some outstanding saves when it matter. De Gea has probably won United at least 10 points this season with some of the saves he has made, Ospina and Szs will never be able to reach that level, which is gutting considering Szs and De Gea were practically identical in terms of stats last year. I'd love nothing better than us to buy Lloris for like £25mil from Tottenham, just as a **** you to put them back in their place. Forster or Cech wouldn't be bad options either if they become available.
