Sevilla president Jose Castro is confident of coach Jorge Sampaoli's commitment.

The Argentine has been linked with Barcelona for next season.

But Castro said he believed the coach, whose current deal runs until June 2018, would remain loyal to Sevilla.

"I trust that Sampaoli will say yes to the offer we have made him to extend his contract for one more year, but we're focused on a complicated week," he told radio station Cadena Ser on Tuesday.

"We don't have to think about Barca or anyone else. He's said very clearly that he came here because we were the club that had faith in him to bring him across the pond and that he's very happy at Sevilla."
