Retired Australian opener Matthew Hayden has hit back at S Sreesanth by describing the Kings XI Punjab pacer as an over-rated bowler who "always loses cool under pressure" following the duo's face-off in their Indian Premier League match yesterday.

"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.
