Middlesbrough have dismissed reports they are seeking to restructure payments over Gary O'Neil's transfer from financially-troubled Portsmouth.
The 26-year-old was the subject of a transfer believed to be worth between £4million and £5million in 2007. It was claimed on Sunday that Boro were seeking to renegotiate the final £1million, due when O'Neil has made 100 appearances.
He has now played 99 games and Pompey, who are in administration, are reportedly angry at the prospect of the original contract being amended.
A Pompey spokesman told The Sunday Mirror: "The administrators are absolutely furious.
"They have told Middlesbrough in no uncertain terms that they will take legal action if they fail to honour the contract in place."
Middlesbrough insist they have no intention of reneging on the deal.
Boro chief executive Keith Lamb said: "I am surprised by the comments attributed to a Portsmouth spokesman.
"All of our payments to Portsmouth relating to Gary's transfer are up to date and I can assure the club and their administrator that should any further payments become due under the terms of the transfer then we will of course honour them.
