A couple more suggestions Marshall:
I forgot one player at Soton which deserves a slight upgrade in CA: Jose Fonte. He is not world class, but he has played well for an (overperforming?) Soton this year. He and Lovren makes a good centerback pairing. He should be better than what he currently is in the game.
Matt Lowton @ Villa should be slightly faster i think. And maybe a slight increase in passing aswell. He has really good vision on the field.
Cardiff: Frazier Campbell has been decent. Maybe a slight CA increase? Jordon Mutch is also rapidly improving his performances, maybe a tidy bit better aswell.
Stoke: Arnautovic should have teamwork upped a bit. 5 is too low. His mental stats in general seem really low. Been pretty good for Stoke imo, on an below average team. Begovic should get positioning increased slightly imo, maybe to 15. He is real quality and has been for a couple of seasons.
Sunderland: Is it possible to remove Dossena from the game? Horrible player and a horrible tackle last weekend.
West Ham: Mark Noble should maybe get one or two up on speed. And should have a higher tackle stat. He often plays more or less as a ball winning midfielder.
Liverpool: Coutinho should have PPM "Tries killer balls often" or what is called. He tried 10-20 trough balls against Arsenal alone. IMO, dont get mad Liverpool fans: Lucas Leiva is a bit overrated in the game. His pace has been well off several times this year etc. But thats your call Marshall. Wisdom on the other hand is rated a bit poorly or? I know he has been loaned out to the championship, but still. Kolo Toure slight increase? He has actually been good this year. Henderson work rate should be increased.
Arsenal: Kieran Gibbs should be improved. He has played well, and is not close to being real quality in the game IMO. Flamini should be a bit better. Giroud slightly better technically. Bellerin and Gnabry should be better. Zealem and Crowley should have better CA, as they are (despite HUGE PA) not close to being good players atm in the game.
City: Kolarov higher Positioning. Other changes have been mentioned by others. George Evans on Under-21 is on loan to Crewe until february 2014. He was on the bench several times last year and seems a real good prospect. Has been playing steadily for Crewe I think (can anyone confirm?). Should have a large CA/PA increase. Shaun Facey @ U-21 the same.
These are a bit more controversial I guess.
