Italian ailing giants Inter Milan hit back at Fiorentina after the latter's vice-president allegedly said Inter should be relegated over their pursuit of Egyptian winger Mohamed Salah.
Paolo Panerai said on an unverified Twitter account that Inter "should be relegated" for trying to poach Salah and had a "lack of transparency".
Salah rejected Fiorentina's offer to extend his loan deal, with widespread reports suggesting that he is on his way to Inter Milan from English Premier League champions Chelsea.
Inter, who did not officially confirm that they would sign the Egyptian international, issued a strongly worded statement on Sunday to respond to Panerai's accusations.
“F.C. Internazionale announces that it has read with great astonishment the comments made by the Fiorentina vice President on his personal Twitter account," read the statement on the club's official website.
"It is not acceptable for anybody to talk out of turn about our club, casting doubt over its solidity and transparency. It is not acceptable for anybody to offend our club and, as a consequence, our fans, with comments that are utterly lacking in foundation.
"F.C. Internazionale is dismayed by the request for exemplary sporting action to be taken against the club, given that it and many other clubs has just signed a public agreement with UEFA to respect the FFP regulations.
"Given that Fiorentina is clearly attempting to involve Inter in a matter that doesn’t concern it, in order to cover up a problem between Fiorentina and the player Mohamed Salah, F.C. Internazionale will make recourse to any authority necessary in order to protect its image and integrity."
Salah made an impressive impact in Florence after joining from Chelsea on loan last January, scoring nine goals in 26 appearances in all competitions as Fiorentina finished fourth in the Serie A and reached the Europa League semi-final.
Fiorentina said recently they would take a legal action against the 23-year-old for declining to report back for pre-season training.
