The midfielder is looking forward to the game, with new boss Slaven Bilic set to be watching from the stands.
The Hammers take on FC Lusitans in the first leg of their Europa League first qualifying round tie on Thursday evening, having qualified for the completion via the Fair Play League last year.
Despite being drawn against lowly competition, in the form of their Andorran foes, the game has proved to be eagerly anticipated, with the club selling nearly 35,000 tickets, and Poyet says that demonstrates that they will be filling the Olympic Stadium when they move from their Upton Park home in 2016.
“It says a lot about the type of fans we have at the club,” he told West Ham TV.
“We’ve got our first qualifier and it’s already sold out. It shows that the new stadium is going to be sold out every week. Some people were saying ‘maybe it will, maybe it won’t’ but 100 per cent it will sell-out.”
The game is coming just over a month after last season finished for West Ham, meaning they are starting their 2015/16 campaign much earlier than their Premier League rivals.
That early start will see the Hammers fielding a youthful side in their first round tie and it will be a big opportunity for those starlets to make an impression on new boss Slaven Bilic, who will be watching from the stands.
Poyet is one of those looking to kick on and challenge for a first-team place and says he is looking forward to the game.
“I’m really excited for the game,” he added.
“I obviously had a really short break on holiday because of the Under-20 World Cup, but I feel good. We’re already prepared for the game and we know as much as we can know about the opposition and we’re ready.”
