Middlesbrough chairman Steve Gibson says his club has been damaged by the protracted selection process that led to his manager Steve McClaren being appointed to England’s top job. In a radio interview on Friday he also criticised David Dein’s role in the choice, suggesting the Arsenal vice-chairman, who sits on the FA board, had shielded his own coach Arsene Wenger from being pursued for the post. Gibson, whose club play Sevilla in the UEFA Cup final next week, must look for a new manager before the start of next season. “It has taken so long. Has it damaged our football club? Definitely,” Gibson told BBC radio.
