A spokeswoman for Tsuna on the island of Awaji said: "We think we have enough budget to fund the camp through the first round of the tournament.
"But if the English team does well and keeps winning in the knock-out round, our budget might fall about 19 million yen (£100,000) short.
"As one possible way of covering the expected shortfall, the
mayor has said he was considering selling the town's gold bullion,"
she added.
Tsuna's people need not fret. England will have to turn in some golden performances of their own to stand any chance of staying - and that may not be possible if Mr Goldenballs himself is unavailable.
Breakfast gamble
Betting shops in the UK are to open at 0700 BST to satisfy the cravings of World Cup punters.
Up to 100 branches of William Hill will be ready to take bets on England's game with Nigeria, which kicks off at 0730 on 12 June, and the Republic of Ireland-Cameroon clash, which starts at the same time on 1 June.
Spokesman Garham Sharpe said: "Some members of staff have already pledged to wear pyjamas, and we will be laying on tea, coffee and snacks for customers.
"However, we don't anticipate serving French bread, Belgian buns, Danish pastries or Turkish delight as we wouldn't want to be accused of favouritism."
