West Ham United boss Slaven Bilic has warned the club needs more than Stratford stadium to move up a level.
The Hammers have made a strong start, sitting third ahead of Saturday's trip to Sunderland, and Bilic wants to ensure it is not just the new stadium that excites fans in 12 months' time.
"If you go to a nightclub and have to pay hundreds of pounds to walk in, you can't go in with £100 - you're going to have to go to the toilet to drink water," Bilic said.
"We have a great stadium now but the stadium by itself will not make us a big club.
"Today you can't become big without one but it's not only the stadium, it is everything - the whole infrastructure.
"When you are building houses you need a school, a hospital, a cinema, a swimming pool - it's the same with a club.
"When you're building a club you need a team to match that. You can't expect the same team to play better just because you move into a stadium."
