Sevilla are considering taking legal action over Vitolo’s move away from the club after the winger u-turned on a verbal contract extension with the club.
The Spain international completed a €37.5m move to Atletico Madrid on a five-year deal earlier this week, but will spend the next six months on loan at Las Palmas due to Atleti’s player registration ban.
Sevilla president Jose Castro had announced earlier this week he had agreed a new long-term deal with Los Rojiblancos but this later turned out to be a ‘verbal agreement’ rather than a signed document.
"The club will exercise its rights, will study the documents within its power and will take all the actions in its hand to defend itself," Castro told Sevilla FC radio.
"Sevilla reached an agreement with his agents, the document was not signed but the conditions were approved. We will defend our interests as far as is necessary, the board will decide how far we go."
