Jack Butland insists he is ready to play at the highest level thanks to his summer spent at the Olympics and Euro 2012.
Liverpool, Everton, Southampton and West Ham are all interested in Birmingham's teenage star, who made his England debut against Italy in August.
The 19-year-old keeper is valued around £6million and Blues boss Lee Clark may have no choice but to sell up due to the club's financial struggles.
And Butland reckons he will have no problem in stepping up from the Championship when the time comes, having already performed under intense scrutiny for Team GB during the London 2012 Olympics.
He was also part of Roy Hodgson's squad in Poland and Ukraine last summer but did not make it onto the pitch.
'I have got confidence in my ability, I would always back myself,' Butland told the Mirror.'I have been fortunate to play in quite a few big stadiums and I'd like to think I have handled myself very well.
'I don't think the occasion would be a problem. I'd back myself and my ability. I want to be playing at the top level for as long as I can in my career.'
