FC Utrecht are angry with Swansea City over the sale of Michel Vorm to Tottenham.
The Daily Mail says Swansea and FC Utrecht are embroiled in a bitter financial row over Vorm's move to Tottenham.
The Dutch club secured a 30 per cent sell-on clause when they agreed to sell the goalkeeper to Swansea in 2011.
But FC Utrecht are still waiting for their money due to confusion over Vorm's switch to White Hart Lane.
The Dutch club has started seeking legal advice in an attempt to resolve the issue.
