#5 Alberto Aquilani
Alberto Aquilani made a real impression when he started his career with AS Roma in the Serie A. He played so well that Liverpool legend John Arne Riise branded him 'better than Xabi Alonso', and Francesco Totti called him “potentially one of the best players in the world”.
The then Liverpool manager Rafa Benitez had so much trust in his talent that he sold Xabi (against his will) to Real Madrid. The Italian though never fulfilled his promise and left Liverpool on loan to Juventus and then AC Milan.
When he returned to Merseyside, his performances didn’t warrant him a starting place, and the English giants decided to cut their losses to Fiorentina. At the end of his spell with Fiorentina, the Italians decided not to renew his contract and he eventually moved to Sporting Lisbon.
At Sporting too he met a similar fate, and the once promising player now plays for Sassuolo on loan from Pescara.
