But if you look at what Rooney has accomplished already. He will probably end up being the leading goal scorer for England, he has won the EPL title 3 times, the CL, FA cup and Club world cup. He has been playing regularly in the EPL since he was like 17. He is recognized as the best english forward and one of the best players in the world by many in the football world.
Amauri is a good player but he is not world class. He has not won anything at the highest level and only just begun to prove himself at a top team at the age of 27. Rooney is 23 and has done more than Amauri probably will in his career. He has played over 50 games for his country. Amauri still has yet to be played by Brazil (can't play for Italy yet).
Anyway I am not trying to diss Amauri but comparing the class of Rooney to Amauri is a bit of a stretch imo.
