Juventus goalkeeper Gigi Buffon says winning the title is the "greatest moment of my career".

Buffon feared he'd blown their chances after last week's gaffe against Lecce, but victory at Cagliari last night earned Juve the Scudetto.

"It's pointless saying that error didn't weigh on me or leave a mark. More than anything else, I was afraid I'd be responsible for someone getting tense or afraid in the final sprint. This is why I had a very bad time the last three days.

"They were the three most horrible days of my sporting existence. I was afraid I had thrown away the title with my own mistake. I felt a great sense of responsibility.

"So tonight, without doubt after the World Cup, this is the greatest joy of my sporting life. Finally it can give a sense to the phrase that hard work pays off. I always thought it was 20 per cent true and 80 per cent rhetoric, but now I think it's 80 per cent true."
