He was too good too early and fell out of love with the game, hence the abnormally early decline. I’m really annoyed that he came back when he did. Not only was the timing bad because of the signings we made, he had declined into a fraction of the player he used to be. This is also why you exercise caution when signing older players.
I think the reason for his early decline is largely down to his early rise tbh. Done people develop before others and physically Rooney was prem ready at 15-16 yrs old. He was bald in his early 20's and he's probably got the legs of a 38 yr old now. His lifestyle choices havnt helped but I have always said that Rooney will be finished before most players simply due to how quickly he developed when younger
