Really mate. I think you should read up in what went down. As I've said numerous times. He was offered a 2 year contract. If he was so bad, he wouldn't have been offered one. He was already lining players up for the summer.
He was homesick. De Laurentis even offered to buy Rafas family a home in the heart of Rome and find a top English speaking school for his kids and a promise of a big spend that summer. Rafael turned it down. He was then offered a rolling 1 year deal, in which he could leave at any point at the end of a season, he was adamant he wanted to return to England. In which he did.
De Laurentis and Rafael are on very very good terms to this day, so much so that he has approached Rafael on 3 seperate occasions to come back, twice in the last year.
