I couldn't really explain the subject in the title box
What I mean is, players who arrived on the scene that looked like they would have a sensational career, but just didn't make it big.
To "kick off"...
Danny Cadermarteri - seemed to be the coming of something special as an Everton youngster, then just slowly faded away.
John Harley - I thought he had it all when he started at Chelsea - where is he now [
]
Any others?
