Del Potro dismisses Nadal threat

In an astonishing interview, Del Potro dismissed the threat of Rafael Nadal - not even bothering to mention the Mallorcan when questioned about the challenges ahead.

"I'm starting out but my new dream is to be number one," said the Argentine. "Roger is still a cut above the rest and Andy Murray is having a great year. I'm trying to close the gap."

Yet more evidence that the Argentine has cracked Nadal’s game and feels he no longer even deserves consideration.
