Sevilla president Jose Castro has confirmed a buyout clause in coach Jorge Sampaoli's deal.
Sampaoli is favourite to succeed Luis Enrique as coach of Barcelona at the end of this season.
However, Castro has revealed they've opened new contract talks with the Argentine, who's current deal runs to 2018.
The Sevilla supremo also admitted Sampaoli's agreement currently has a break clause.
"His clause now is €1.5 million," Castro said. "We have offered another year on the contract to Sampaoli."
