Mallorca president Vicenc Grande has revealed that he has held off on reporting Portsmouth over their approach for Jonas Gutierrez, but accused them of manipulating the player.
Pompey were reported to have made a €10million (£7million) bid for the 24-year-old Argentinean forward, but that has been refuted by the Balearic club's supremo.
Grande is incensed by the saga and accused the Premier League side of making an illegal move for Gutierrez.
"Portsmouth do not want Jonas as they have insulted the player by undervaluing him and manipulating him," he stated.
"They are not complying with Uefa laws, which state you cannot negotiate with players if you do not have permission from their clubs.
"At the moment we are being prudent and have not taken any measures."
Mallorca share 50 per cent of Gutierrez's rights with Argentinean side Velez Sarfield, so any bid would have to be approved by them and that has left Grande mystified by Portsmouth's move.
"No club has offered Mallorca €10m for Jonas," he continued.
"There was one offer of €5m (£3.5m) and another for €6m (£4.1m) and I do not know how the payments would have been dealt with as we only own half of his contract.
"Jonas is a magnificent player, but we will not negotiate through the press.
"He has two-and-a-half years left on his contract and he will have to complete those with Mallorca, with Velez or wherever because his federative rights are ours."
