West Ham United and their London Stadium landlords have reportedly clashed over who should pay for Sky TV, draught beer and hospitality staff.
The Hammers are already due to contest a lengthy court case with London Legacy Development Corporation (LLDC) later this year after being denied the chance to extend the ground's capacity.
According to The Times, United are now embroiled in a fresh row with the publicly-owned body as they feel that they are being denied services promised to them under their rental agreement.
West Ham are said to have asked for LLDC to install draught beer pumps in every bar, which they have refused to do, and they are also unhappy with having to foot extra money to screen Sky inside the stadium.
As well as rowing over staff costs, the report also suggests that United must cough up £200,000 of their own money to replace the green cover over the running track with a claret-coloured one.
