I think I'm still waiting for Bojinov to come good tbh. Emile Mpenza is the one that stands out for me though, just because he was possibly the best striker in the world on Champ Manager 01/02, which I played an ungodly amount as a kid, so when we signed him I knew it was fate that he'd be bagging 20 a season for us for the next 5 years, just as he had on my Champ manager save. Not quite how that turned out (to be fair, all his hype was in my own head, I don't think anyone who'd actually seen him play in the previous few years was remotely excited at the thought of him playing for City)
