Craig Bellamy will not be afraid to ruffle feathers in the West Ham dressing room next season despite his problems at previous clubs.
The Wales striker has a reputation for attracting unwanted headlines and was involved in high-profile incidents at Newcastle and Liverpool.
Yet that did not prevent West Ham paying £7.5million for his services this summer and the 28-year-old appears to have no intention of mellowing.
Bellamy said: 'What happens when you step over the line? Is that wrong?
'One of the best dressing rooms I have been in was at Celtic.
'There were fights and arguments every week. They won everything and got to the UEFA Cup final.
'They were all close friends but they demanded things from each other. Are you out of order if you demand too much from your fellow workmate? I don't know.'
