England paceman Steven Finn says there is no chance of England underestimating Australia in this summer's Ashes series.
The first Test starts in Trent Bridge next Wednesday and Australia are seen by many experts as a team in crisis.
Thrashed 4-0 in a Test series India earlier this year, they failed to escape the group stages at the recent Champions Trophy and then changed head coaches just three weeks before the Ashes.
However, Finn said: "I think it would be foolish to underestimate the Aussies.
"They are always a very competitive team and have got some excellent cricketers. We can't allow ourselves to think it is going to be easy, by any stretch of the imagination.
"We know that if we play our best cricket we can win the Ashes but it is going to take a lot of hard work and fight from our side to make sure that happens.
"It doesn't matter what people are saying outside of the dressing room, all that matters is what is said inside the dressing room and what happens out on the pitch."
Fire in the belly
Finn appears to be battling with Tim Bresnan for a place alongside James Anderson and Stuart Broad in England's seam attack for Trent Bridge.
And he added: "I missed most of the Champions Trophy just by being left out, so I suppose it gives you a bit of extra fire in your belly to make sure you don't miss out on the big games in the future.
"I was disappointed to miss out on so much of the Champions Trophy but you learn from it and move on, and hopefully I will play a bigger part in this Ashes series.
"Ultimately the most important thing is the team, I want to play as big a part as I can in winning us the Ashes but, if Tim plays ahead of me, then I'd be happy for him."
Broad feeling great
Broad, meanwhile, is raring to go, having missed the last three Tests of the series when England won 3-1 in Australia in 2010/11.
"I would be going in all guns blazing even if I had never played an Ashes Test before but I went home after the second Test with a torn abdominal last time," he said.
"It was heartbreaking to leave that Ashes tour so of course I want to have a big impact on this series.
"But you can't put too much pressure on yourself because cricket is one of those sports where you could get hit in the face or break a finger.
"I would love to stay fit and I'm feeling good at the moment. I'm really hoping for a successful series.
"In the Champions Trophy final I dived to get into my crease and, as a tall, gangly guy, my shoulder just locked. It only really hurt when I got to the top of my bowling action but it has cleared up really well, I have no worries."
