England's match against Trinidad and Tobago next month could be called off because of a dispute over the stadium, according to a report.
However, the federation responded angrily, insisting that figure did not match the original agreement between the parties reached in March.
The federation has now issued an ultimatum to the Minister of Sport and Youth Affairs, Gary Hunt, demanding that his department honour the original agreement or face legal action.
According to the Trinidad Express report, the federation's attorney, Om Lalla, has written to the ministry demanding that it indicate whether it is "prepared to honour the terms of the agreement of the 15th March 2008", giving a deadline of Friday morning before he initiates legal proceedings.
Lalla warned that failure to honour the original agreement "will cause irreparable damage to reputation of the TTFF and subject each and every citizen of Trinidad and Tobago to shame and humiliation, and will result in a breach of contract with the English FA and may result in a cancellation of the match".
