Stuart Broad has warned his England teammates to not get carried away as they close in on a famous Ashes triumph.
The Three Lions opened up a 214-run lead over their opponents in the fourth Test after a memorable first day at Trent Bridge.
Broad himself took a career-best 8-15 to help bowl the tourists all out for 60, leaving England on the brink of a series victory heading into day two in Nottingham.
"We've been conscious all week not to talk about winning The Ashes - because I think that mentally takes you to quite a dangerous place," he told Sky Sports News.
"[Alastair] Cook said again at the end of the day's play 'Let's enjoy the next hour in the changing room; we've had a fantastic day, one of the best England have had in The Ashes ever - but let's reset for day two'."
England lost the last Ashes series 5-0 Down Under two years ago.
