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 in Melbourne 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. An Australian team going through a re-building would live up to the expectations in the series, he said.
"I think it's going to be an interesting and exciting time for Australian cricket with the young guys putting their hands up.
"I think the first thing is who's going to be selected in the team and when they (India) come out I think the brand of cricket Australia plays we'll be right over here," he said.
McGrath did a yeoman service to the Australian team before leaving on his own term. Commenting on the current pace attack options, the 'Pigeon' said Australia faced a problem of plenty.
"It will be interesting to see which way they go. The way Mitchell Johnson has bowled over in India - he's definitely put his hand up. Brett Lee's coming back, Shaun Tait's down in South Australia there and is coming good again.
"You look at the next 18 months, two years, there's a lot of cricket so I dare say there's going to be a big turnover in players."
He, however, was not that sure about someone filling the void created by Shane Warne's retirement even though he praised both Stuart MacGill and Brad Hogg.
"Warney is probably a different kettle of fish. "We've got a couple of front-line spinners - the way Stuart MacGill's showed his form through his career, Brad Hogg the way he's bowled - so I think it won't be too bad in the near future," he said. "We'll see how the younger spinners come through and that will be key for Australia," added McGrath.
