Hey Frankie mate, I considered few players attributes a little unrealistic.
Lennon's attributes are too low, really, he is a great Winger and his stats are poor.
Walcott is even better (yes he is), but that stats don't make him a good player.
Agbonlahor & Carew are a little under-rated and they need a little growing in the attributes.
Palacios needs a little of work on his tackle and on the positions (he can play as DMC too).
I think the injures must be taken off and there must be add the new injures. I hope this helped a bit I am gonna check some new players and see if they are rated corectly. If you need my help, PM me.
