While I dont disagree with you per se - how many trophies have the above players won? How many league titles?
I wouldnt call George an experienced player. Ok, he is 25, but only has been playing in this league now for little over 2 years, after being a bit part player in the UK. Thats not to say he isnt very effective and a vital part of the team though.
Greg may be experienced, but thats not to say that they are all good experiences. Look at his City career. It has been checkered to say the least.
