It seems an appropriate time for Buffon to retire, having previously stated he would walk away at the end of the season unless Juventus won the Champions League - a dream that was crushed in dramatic fashion at the quarter-final stage after he was sent off for a foul in the area and Real Madrid converted the resulting last-gasp penalty. I'm proud to have played to the best of my ability right up until now, with performances which befit both myself and this club.
"I said that I received very interesting offers", said Buffon, when asked directly about a move to the English Premier League. "Now offers have arrived that are exciting on and off the pitch", he said without discussing where he could be headed.
'Until a few a days ago I was certain I would retire from football. If my future lies off the pitch, it will be necessary to undergo a training course in order to understand the right path to take and what role I could occupy.
"If I decide to continue it will be to fight for big things, because that's what I live for".
Despite previously having opportunities to test his skills in other areas of the world, Buffon turned them down and admits it is a slight regret when reflecting on his career. Gigi's eyes don't give me the feeling he wants to stop.
