The Hammers coach has opened up about the most frustrating aspect of his work at Upton Park.
Allardyce, 60, has recently seen his team undergo a series of games without a win in all competitions, with what looked like a very promising season indeed turning into a somewhat mediocre one - West Ham currently sit 10th in the top flight.
And the Hammers boss admits a lack of spending power compared to the biggest clubs in the division holding the east London side back is the most frustrating aspect of his job at Upton Park.
West Ham lost 1-0 to Chelsea on Wednesday night but have previously proven their credentials against the likes of Manchester City, Liverpool and Manchester United.
Asked what his biggest frustrations are, Allardyce told Sport: “At the moment, there’s a level we can reach. But it will be very difficult to go beyond that based on the spending power of the big guys now.
"That is probably a frustration as a manager. You can beat the big guys: we drew with Manchester United [thanks to a stoppage-time equaliser], we beat Liverpool, we beat Manchester City. But not to be able to beat them on a regular basis is one of the frustrations for me.”
West Ham can now enjoy a several-day break as they aim to get their campaign back on track. When they return, they'll travel to the Emirates Stadium to face Arsenal, before hosting Sunderland at the Boleyn Ground a week later.
