Fiorentina chief Pantaleo Corvino admits missing out on Manchester United pair Nemanja Vidic and Nani were among his biggest regrets in the transfer market.

"I say Vidic, who had signed with us but then had to wait until January because of his non-EU status," said Corvino. "Then Breno, who went to Sao Paulo despite our offer of £10 million. Bayern Munich then offered £13 million and he was taken.

"Then there's Ricardo Quaresma and Nani."
