Rafael Nadal said he was oblivious to the barbed exchanges that took place between Andre Agassi and Pete Sampras at the 'Hit for Haiti' on Friday night.

Nadal played doubles with Agassi, but said he didn't understand what was being said between the two Americans because they were talking too fast for him to understand. Sampras imitated Agassi's pigeon-ted walk while Agassi portrayed Sampras as a bad tipper, reigniting their conflict over Agassi making the same claim in his best-selling autobigraphy last year.

“I didn't understand nothing. No, that's the truth," said Nadal. "They speak very fast for me. you understand what they said. I didn't understand. I didn't feel any tension.”
