West Ham are threatening to sue the owners of the London Stadium, if there is no cut in beer prices before the next home game.
The club are furious that the cheapest pint of beer for the opening match against Manchester City was £7.30 – up £2.11 from an equivalent purchase at neighbouring Tottenham.
They are willing to go to court to force a price change, citing the Comparable Clubs clause in their catering agreement with the London Stadium.
Fans were angry at the prices being charged on the first day of the season – but West Ham do not set those prices and do not profit from catering at the stadium.
