Sunderland are holding out for a particular sum while Lazio continue to pursue winger Jack Clarke, according to reports in Italy.
The Black Cats face the danger of losing one of their greatest players before the transfer market closes on Thursday night.
Clarke has emerged as a top target for Lazio in the last days of the transfer market, and the Serie A club is attempting to complete a deal for him.
Sunderland have already turned down a €16 million offer from Lazio for Clarke, indicating that they are firmly committed to him.
According to Italian daily Il Messaggero (via Calciomercato.com), the Championship team is demanding a fee of roughly €25 million for Clarke.
Tottenham Hotspur have a 25% sell-on clause, and the Black Cats would have to consider that before agreeing to transfer him.
Lazio are convinced of the winger’s quality and will continue to push for his signing in the coming days.
They are set to try a different strategy to lure Clarke away from Sunderland before Thursday’s deadline.
