4. Valeri Bojinov
Football Manager nuts will be well aware of this guy, who looked set to become a world class striker when he arrived at Fiorentina in 2005. He joined Manchester City two years later and has never fully recovered. Bojinov is still only 28 years old, but he is currently slumming it in Italy’s Serie B with Ternana. Surely, he has one big move left in him?
