Not "Lottoland Oval" or "Lottoland Stadium".

Ah...Lottoland. 

The Sea Eagles' historic home ground will change its name in a deal that is expected to be finalised early next week.

The online lottery company will be advertised on giant 85-metre billboard erected on Pittwater Road.

Sea Eagles chief financial officer Neil Bare says fans will support the move to "save rugby league" in the region.

"This is the first step towards the upgrades," Bare told the Manly Daily.

The Sea Eagles have secured $25 million in state and federal funding for a 4000-seat stand.
