Sevilla have attacked Tottenham for the 'treacherous' way they landed manager Juande Ramos.
The Spaniard was appointed as Spurs boss over the weekend following Martin Jol's departure from White Hart Lane.
It ended months of speculation that Ramos had been lined up by the Premier League club and Sevilla are unhappy that there was seemingly contact between the two parties before they had given their permission.
Sevilla president Jose Maria Del Nido believes Spurs' swoop was illegal and looks set to take the matter to Fifa and Uefa in a bid to get compensation.
"They will get the response they deserve from Seville," Del Nido said in The Sun.
"We will channel our energy, force and all the means available to us into making sure Tottenham pay the consequences of a situation they have illegally and illegitimately provoked.
"Here in Spain we're not used to treachery between football clubs. You'll see what we do with regard to Fifa."
Alves and Kanoute link
Ramos has been tipped to raid his former club in the January transfer market to help turn around Tottenham's flagging fortunes.
Daniel Alves and Fredi Kanoute have both been linked with Spurs but Del Nido has warned Ramos off the pair.
He said: "I doubt very much that Tottenham have the money to buy them."
