West Ham United co-chairman David Sullivan is disappointed with the commitment of the Premier League's American owners.

He has mixed feelings about certain foreign owners, his views influenced by the erosion of what he considers a boardroom tradition at matches.

"There are good examples of foreign ownership," he told the Daily Mail. "Man City and Chelsea are terrific. But if things go bad for a foreign owner it's easy to walk away.

"Roman Abramovich and Sheik Mansour are in it for the fun. It's a hobby. Randy Lerner is here to make money.

"The Americans at Man United and Liverpool are here to make money. The Sunderland guy has a strategy to make money. But when it comes to the boardroom you rarely meet them. It's sad. In the old days it was lovely. There would be banter but you'd also exchange ideas, share thoughts. But the new brigade, you don't see."
