West Ham United co-owner David Gold is "optimistic" that the club's new Olympic Stadium home will sell out on a regular basis when they make the switch next year.

The Hammers will say goodbye to the Boleyn Ground at the end of the 2015-16 season, upon moving to the redeveloped 54,000-seater venue.

Gold admits that leaving their current 111-year-old stadium will be tough initially, but he believes that the club will only benefit from the change in the long run.

"Leaving the Boleyn Ground will be an emotional time," he told BBC Sport. "It will be a momentous event for anyone affiliated to the football club.

"Obviously, attendances have a lot to do with performances on the field, but taking all things into account we are optimistic of filling the stadium, 99% of the time.

"Every time we get an update on ticket sales, they are the best we have experienced. All the targets we have set ourselves are being met."

West Ham's final game at the Boleyn Ground will be against Swansea City on May 7.
