sreesanth should perform -mcgranth

Having talked the talk, volatile Team India pacer S Sreesanth now needs to back up his aggression with performance and prove his worth, said Australia's former spearhead Glenn McGrath.

Though no more part of the team, McGrath keenly followed Australia's just-concluded one day series against India, which saw heated altercations with Sreesanth featuring in quite a few of them. McGrath said it was high time the youngster delivered the goods with the ball.

"At the end of the day you've got to be able to back it up. You can talk the talk but if you can't go out there and perform then you're not going to be around for very long," McGrath was quoted as saying by 'The Australian'.

The lanky pacer also doubted that Sreesanth's on-field aggression was not natural at all.

"I've had a chat to him a few times and it doesn't seem to be in his character," he said.

"He's trying to be aggressive and it's a little bit unusual.

"You want your fast bowler to be aggressive. Giving blokes send-offs or sledging when you talk back I don't agree with but that's up to the officials to sort out," McGrath said.

And he warned the Indian team to expect enough hostility when they arrive here later in the summer to play four Test matches.

"The Indians really don't like the quicker or bouncier wickets so we'll wait and see what happens.

"I'm sure they'll come and try to be aggressive but I think no-one does it better than the Australian team," McGrath said.
