David Sullivan has ruled out appointing Paolo Di Canio as the new manager of West Ham.
The 42-year-old Italian has been linked with the vacant post since Avram Grant was shown the door on Sunday after the Hammers' relegation to the Championship was confirmed.
But the club's co-owner Sullivan says the former Hammers striker does not fit the bill due to his lack of managerial experience.
He told Sky Sports News: "The problem with Paolo is, although the fans would love it, I'm being realistic and he has no experience whatsoever being a manager.
"If you look at first-season managers the failure rate is enormous.
"If he'd done a season anywhere and was, say, top of Serie B in Italy with a team, I'd take the chance.
"My heart would say Paolo and the fans would say Paolo.
"But with someone who's a complete novice as a manager, with no experience, you just can't go with it."
Sullivan has revealed West Ham are leaning towards appointing a British manager, with Chris Hughton, Martin O'Neill and Sam Allardyce among those believed to be in the frame.
He added: "I think we'll definitely get an English manager, or a British manager.
"We do need someone who understands the culture and if you get someone with a knowledge of the East End that's so much better.
"We'll wait to see who applies and wait to see what happens generally, but it will be resolved within two weeks, I should think."
Sullivan admits appointing Grant as manager last summer was a 'bad selection' after a dismal campaign.
He said in The Sun: "Avram is a lovely person but the results sadly speak for themselves that it was a bad selection by the board.
"We all share some blame for the results - the board, the manager and the team. However, the team can only play the tactics and formation they are asked to play.
"We want a manager who will get the best out of the squad and foster a strong team spirit."
Who should be the next West Ham manager?
