West Ham United boss Sam Allardyce is convinced a potential move to the Olympic Stadium will make them bigger than Liverpool.

Big Sam knows first-hand how moving to a new stadium can propel a club forward - after he oversaw Bolton's switch to the state-of-the-art Reebok Stadium back in 1997.

He said: "If you want to be one of the big boys in this league, as great as Upton Park is, if you've got the chance to move on you should. There's always a lot of disruption when a club decides to move from a place with huge history. It's always going to be upsetting for some of the many loyal supporters.

"But when you look at what happened at places like Bolton, I couldn't have built that sort of success without those fantastic facilities.

"For me it's to try to build a new history. You never forget what's happened before, it's instilled in the club, but you want to build a new history for young fans. They want something to remember when they get older."
