Broad, 31 and no stranger to Ashes controversy having been constantly heckled during the 2013-14 series, said the Australian's words could fuel England's bid to retain the urn.

"Warner's a very competitive guy... He's already talked about the Ashes being like a war for him and we can use that to help us."
Broad, who became England's second highest wicket-taker this year, said the team were completely focussed on preparations for the series.
