Ex-Toon Defender Gets Manager's Job
Pearce staked his claim for the job by taking England to the semi-finals of the tournament last month in Holland, where they lost in a marathon penalty shoot-out to the hosts.
Pearce: "The fact it's a full-time role excites me. Looking to the future it will more helpful.
"Every game you learn as a manager, I'm a wiser man than I was two years ago."

Stuart Pearce - 'Barton HAD To Leave City'
By Nu Mad Wednesday 18th July 2007
There has been a minor "war of words" between Joey Barton and Stuart Pearce, with the ex-Man City boss saying Barton "had to leave City", and the new Toon player saying "I'm saying nothing" ... but saying quite a lot!

Barton left Manchester City, where he began his career, in a £5.8m move this summer. During his time in Manchester the tough-tackling midfielder saw loads of controversy, but Stuart Pearce said Barton's training ground bust up was the end of the road.
The two fell out after Barton allegedly assaulted team-mate Ousmane Dabo in a training ground confrontation, which the former England skipper saw as the last straw.
Pearce (who had by then been sacked as manager): "If I was in charge, I'd have done the same on the grounds that I don't think the dressing room would have accepted him any more."
Barton: "I didn't speak to him about moving to Newcastle. We had a relationship breakdown in the end and he came out and said certain things I think he shouldn't have said.
"There's a lot of things I feel about him but I've not come out and said them and I don't plan on doing so. When you have a working relationship with someone there's a lot of things that should be kept in-house. Stuart thinks different and he's entitled to his opinion but if everyone spoke their opinions we'd have anarchy and chaos in this world."
Barton spoke of his move to Newcastle:"I'm an Englishman and nothing makes me more proud than to play for my country. I'm very patriotic.
"I'd love to be in the England fold but I'd much rather be successful here at club level because this is where your bread's buttered. This is where you earn your caps by playing well for the club so the first thing on my mind is to achieve success here. If I do that everything else takes care of itself.
"It's vitally important to get the support of the fans and their appreciation for what you're doing for their club.
"Players come and go and can be ships in the night but if you can leave some kind of legacy to remember you by you've done a good job.
"I had a great rapport with the fans at City and the wrench in leaving was 50-50 between the fans and the club. It's difficult for players these days to get good relationships with fans because of all the chopping and changing."
