Ricky Ponting reckons David Warner must respect Stuart Broad's pedigree but counter him with aggression during the rest of the ongoing Ashes in UK. 

Broad seems to have worked out a chink in Warner's technique and has scalped him thrice in the series in just 29 deliveries. 

But Ponting said the Aussie opener has also missed a number of boundary balls from the veteran English pacer, including three late on Day 2 at Lord's before his dismissal. 

He reckons that was a massive opportunity missed by Warner to put Broad off his current game plan. 

"I think the thing that would disappoint Davey the most was the fact there were a few clear scoring opportunities that he missed," Ponting told cricket.com.au.

"There were a few really wide ones that he would generally pounce on and cut, and there was a half volley that he got a thick outside edge on and went to backward point."

"If he puts those three balls away, it’s a totally different game. You’re off to a flyer and the pressure goes back onto the bowler," he added. 

"The ones that he missed out on were short and wide, which says to me that he wasn't as free in the mind as he should have been. He plays his best when he's playing the ball and hitting the ball hard."

"That's going to be the challenge for him; to free himself up in the mind, watch the ball and react accordingly."

Ponting thinks Warner has been tentative this series and needs to look to score runs rather than worrying about that potential wicket-taking ball. 

It could happen to the best of batsmen, especially in difficult conditions as you encounter in England where the red dukes swings and seams for long periods of time. 

"I spoke to him before the series and he knew that was the way they were going to bowl to him. People think he's just a stand-and-deliver batsman, but there's a lot more thought into it than that," Ponting said. 

"He plans very well and the fact he's batting on off-stump (in an attempt to counter Broad's line of attack) shows he's thought a fair bit about it."

"The problem is, when you’re expecting a bowler to bowl a certain way to you, you tend to only look for that one delivery. He would have just been looking for something that was quite full, pitching on off stump and swinging away," he added. 

"Even the one that bowled him, it looked like he was expecting it to swing away from him. He missed it on the inside."

"It's a hard thing to do to pick yourself up and just go and hit the ball. But that's what he's going to have to do and that's the way he plays his best."

"I'd be encouraging him, if he's going to get beaten, to get beaten on the outside of the bat, not back through the gate. Set up to hit down the ground and just react to it. I know that's what he works on anyway, but I think he just needs reinforcement on that."

"(Facing Broad) is something he can’t get away from, but he’s played enough to know how to get himself back into this series," Ponting concluded.
