These are very exciting times indeed for the Hammers, who are fourth in the Premier League table and are also in the last eight of the Carabao Cup having beaten Manchester United and Manchester City along the way.
And things are looking very encouraging off the pitch with Czech billionaire Daniel Kretinsky reportedly close to buying a stake in the club.
Reports claim 46-year-old Kretinsky is in 'advanced talks' over the purchase of a a 27 per cent stake in West Ham, with a view to a potential full takeover from current owners David Gold, David Sullivan and Karren Brady in the future.
West Ham are also flying high in the Europa League, leading their group with three wins from three games, and billionaire investment would give them a great chance at going to the next level.
And Agbonlahor believes Kretinsky - estimated to be worth nearly £3billion - could do a lot worse than put his money into West Ham, with the former Aston Villa star saying the east Londoners are a bigger club than Arsenal and Tottenham.
"If I was a billionaire I'd be thinking the club is in a perfect place," Agbonlahor told talkSPORT Breakfast. "A great squad, a great manager at the moment."

Agbonlahor added that David Moyes' side should be looking to continue their progress, but will only achieve that by keeping their key players - which will surely be helped by this reported new investment.
"They look like a team that's going to keep getting into the European places," he added. "They're looking a real good outfit, West Ham.
"Apart from Chelsea, they're the biggest club in London. They've overtaken Arsenal, they've overtaken Spurs - and Brentford and Watford!
"But they've now got to hang onto Declan Rice, hang onto Michail Antonio, hang onto Aaron Creswell, hang onto these players and add more to their squad.
"Why can't they start looking at top four?"
