PSV Eindhoven will seek compensation should sacked striker Jonathan Reis sign with another club.
The 20-year-old Brazilian left PSV on Monday after the club claimed he had tested positive for a banned substance and refused to seek help on the matter.
Reis had reported for training in poor condition and was sent to hospital for tests, which is when the banned substance was discovered. As he has not failed an official drugs test, he can sign with another club.
But PSV director Jan Reker said he would then seek compensation, citing the example of former Chelsea striker Adrian Mutu. Mutu signed for Juventus but was then told he must pay Chelsea £14.7 million for breach of contract.
Reker admitted there are some differences between the two cases, not least the fact that Mutu failed an official drugs test and received a seven-month ban as a result. But he believes the principles are the same.
"We have obtained information from all the authorities and the case is relevant,'' he said in De Telegraaf following a media briefing on Monday. "We are entitled to compensation.''
Reker added that the club had no option but to sack Reis, as they feared he would be banned soon enough anyway if they did not.
"We could not risk losing him to a doping test after a game, so we proceeded to act,'' he said.
"These things stay in the body so long, it would mean he could not play again this season.
"He told us he would stop, but this was not enough in our eyes. The drugs are addictive and he needs to go to a clinic.''
