I'm not talking about the likes of Suarez (blatently obvious)... more so players that have established themselves or are in the process of re-establishing themselves...
Begovic - For me, the best keeper in the league. Would be suprised if he's still at Stoke after next summer.
Schneiderlin - Been aware of him for a long time but didn't realise how good the lad actually was. Seems to have a bit of everything.
Lallana - I think he's an ego away from being a top player. Seems to have the lot except arrogance.
Lovren - Solid as a rock, in the air and on the ground, can play a bit too.
Ramsey - Really stepped up a level this season. Not a great player, but no longer seems out of his depth and overawed.
Barry - Everton's best player, people had said his legs have gone, but when you have a brain like him you don't need legs. Exceptionally good so far.
Mertesacker - He's been solid this season (city apart) after the hammerings he was taking last season. Obviously the lad can't run, but he's proven there is a player in there this season.
Schzeny - (however its spelt) Seems to have cut the stupid mistakes out and looks much better for it, starting to look impressive.
Sagna - his crossing so far has been exceptional. David Beckham esque crosses. Truely brilliant. Solid defensively too.
Probably a few more, but thats all I can think of off the top of my head.
