Alessandro del Piero is confident Juventus can shock Inter Milan this weekend - and insists he can play on beyond the end of his current contract.

The Juve captain declared: "The rivalry has been fierce for years, but this time it is the most tense of all, it's almost like we're playing for the Scudetto.

"We have a greater conviction which makes us superior. There's no signs for anyother outcome than victory."

Del Piero added: "I feel in great shape, I do not see why I should consider retiring at the end of my current contract."
