Reina: I want to be Liverpool's best No.1
"At present, I am negotiating a contract extension with Liverpool. I want to be the best goalkeeper in the club's history," he told sports daily Marca on Saturday.
While the undisputed number one at Anfield, Reina has to content himself with being the back-up to Real Madrid's Iker Casillas with the Spanish national team.
"I accept it with resignation," he added. "It's good that in this national team we all accept our roles with grace. Spain has players of the highest quality."
After winning the European championship in 2008, Spain are being touted as one of the favourites to lift the World Cup trophy in South Africa in July.
"There's no point in denying it. But Germany, Italy and Brazil are as well," Reina said.
"In a World Cup everything has to go to perfection if you want to be champions. (It wouldn't be a failure if we didn't win). Failure would be to not make it out of the group stage."
