Spain U21 hero Saul Niguez insists he's happy at Atletico Madrid.

The midfielder hit a superb hat-trick in last night's U21 Euros semifinal win over Italy.

Saul is attracting interest from Barcelona, but at the final whistle he pledged his commitment to Atleti.

"I'm very happy where I am," said Saul.

"I'm very happy, but now it's only time to rest and think about the final."
