West Ham United co owner David Sullivan outside the Olympic Stadium
The Hammers embark on the next phase in their history when they play the first ever game at their new 60,000 seater home in Stratford against Slovenian side NK Domzale in Europa League qualifying on Thursday night.
After 112 years at their beloved Boleyn Ground, it is all change for Hammers fans.
They have fully embraced the move, though, judging by the fact the club has sold out with 52,000 season tickets - second only to Manchester United in the Premier League.
The Olympic Stadium
Generations of matchday routines out the window
But some are understandably apprehensive about the move after generations of matchday routines went out of the window this summer.
How to get there, where best to gets trains or park, where best to eat and drink, how best to get to the new seats are just some of the worries of Hammers supporters ahead of the new season.
Some of those concerns will be allayed, though, by a new initiative from West Ham which will see the turnstiles to the Olympic Stadium open a full two hours before kick-off for every single home game this season, as revealed on the club's official website.
The stadium before its West Ham-ification
'Arriving early will allow supporters the opportunity to find their seat'
A statement on whufc.com said: "Supporters are encouraged to make their way to London Stadium in plenty of time to familiarise themselves with their new surroundings and begin to formulate their new matchday routines.
"With 36 mouthwatering catering outlets inside the concourse and plenty of bars for thirsty supporters, there is every reason to enter the Stadium early to sample what London Stadium has to offer.
"Most importantly, arriving early will allow supporters the opportunity to find their seat and take in their new surroundings at one of the globe’s finest sporting arenas."
West Ham manager Slaven Bilic
Bilic will hope players adapt to new surroundings quickly
The Olympic Stadium is now in full football mode ahead of the opening games this week although capacity for those matches is limited to 54,000 and will then increase to 60,000 thereafter.
Slaven Bilic will be hoping his players can also familiarise themselves with their new surroundings quickly so they can continue the fine progress made under the former Croatia boss last season.
Stadium moves have proved problematic for teams in the past but with an extra 20,000 Hammers belting out 'Bubbles' it promises to be carnival atmosphere at every home game.
