I also think its pointless to try and compare the 2 players as they were at their peak so many years apart and also played in different positions
I lost any respect i had for Rooney at the 2010 world cup when he had a go at England's fans for booing the team after another awful display.
I cant really comment on Bobby Charlton as i never saw him play and have only seen a few clips of his goals on TV either for Utd or the 3 Lions.
My personal favourite is Gary Lineker who was badly treated by Graham Taylor at the end plus i also liked Michael Own and Alan Shearer too.
