Stuart Broad is front and centre of the image which will forever define the 2015 Ashes series.

Wide-eyed, hands clasped over his mouth, the Nottinghamshire seamer looks on in astonishment after Ben Stokes produced a stunning catch to remove Adam Voges.

It was Broad’s fourth wicket of the morning – and he admits it almost derailed his chances of producing a record-breaking performance.

“I don't know if it was the emotion of seeing Stokes take that catch but I lost my run-up,” he told Sky Sports.

“I was stood at my mark forgetting whether I go off my left foot or right. It sounds ridiculous!

“Fortunately, I got it back in the next over. If I ever feel like I have lost my rhythm, I sing a random song as it stops me thinking."

"Stokesy has this finger that we call 'The Claw’. He badly broke it when he was younger and it is almost double the thickness of a normal finger.

“I genuinely think it helps the ball stick in his hand!

“The 2019 World Cup catch [at the Oval, against South Africa] was awesome but I think this one for reaction, for instinct was so special.”

The stoutest resistance from Australia on the day came from Mitchell Johnson, who top-scored for his side with 13.

It was a 25-ball innings which frustrated Broad.

"I remember when I got Johnson or [Mitchell] Starc out that it felt like they had got 70 each and it had been overs and overs.

“I remember feeling relief - that came from how quickly things had happened in the first six overs and how it then felt everything was happening quite slowly.

“What you also didn't want was the last two whacking 30 each as we still didn't know what a good score was.

“If they got 130 and we got 150 the game was still wide open. We wanted to finish the innings as quickly as possible."

"The more experienced I have got I think I can pick up on certain things to try and replicate”

Broad on producing gamechanging spells

With 17 Test five-wicket hauls and two Test hat-tricks, Broad is a man who knows the virtue of seizing the opportunity to change a game.

It is, he says, no coincidence that he has become famed for his matchwinning spells.

"The more experienced I have got I think I can pick up on certain things to try and replicate,” he said.

“A lot is also to do with the run-up - I feel I need energy and my knees picking up in a certain way.

“One thing when I have picked up these wickets in groups is that my mind is always so clear.

“I am not thinking too much about what I am doing, about setting batsmen up, so to speak. I'm just running in, doing the basics well and making batsmen play.

“It's frustrating as you'd love to be able to bowl spells like this every day."
