Adriano and Mutu for me. Especially Adriano who was almost scary in his prime for Inter and Parma. Mutu in his first season with Chelsea looked unbeatable at times. Also José Reyes is a mention, I honestly thought he would be unstoppable after his first games with Arsenal.
Was it just me being young and stupid or did Mario Stanic look really good for Chelsea in his first days there? What happened to that guy?
Bit weird thinking that all those guys mentioned have barely reached 30...
