Atletico Madrid midfielder Koke has played down reports linking him with a moves to Manchester United and Barcelona this summer.
A recent report claimed that United were willing to meet Koke's £48m release clause, as incoming coach Louis van Gaal tries to add quality to his midfield ranks this summer.
However, speaking ahead of his participation with Spain at the World Cup, the 22-year-old moved to pour cold water over the stories linking him with a switch away from the La Liga champions.
"Right now, I'm only thinking about playing football for the World Cup," he told reporters.
"[That is] is the most important [thing]. I have a contract with Atletico and I'm very much at home here. If Juanfran sees me as captain in the Vicente Calderon, you never know in life."
Spain begin the defence of their World Cup trophy against the Netherlands on Friday.
