Retired Australian opener Matthew Hayden has hit back at S Sreesanth by describing him as an over-rated bowler.

Hayden said that the pacer "always loses cool under pressure" following the duo's face-off in their Indian Premier League match here on Thursday.

"Yeah, I think he is a particularly over-rated bowler. And so he was a great target for us to go at. He always loses his cool under pressure and I think it was a good example of that (in the match)," he said.

Hayden hit Sreesanth for three sixes in the 17th over in his innings of 89 before falling to the same bowler. A furious Sreesanth gave a mouthful to the Australian when he was heading for the dressing room.

Hayden, however, refused to reveal what words Sreesanth had hurled at him.

"You don't want to know. It's just so meaningless. Mate ... I am a Test veteran and a one-day international veteran, I have got nothing to answer to him that's for certain," said Hayden who holds the Orange Cap with 378 runs.
