Pepe Reina has insisted he cannot pledge his "eternal love" to Liverpool, and has called on the club's owners to dig deep to fund signings.
Reina is regarded as one of the finest goalkeepers in world football and is a key figure for Liverpool, but the 28-year-old has been frustrated by the club's failure to challenge for honours and was disappointed to see Fernando Torres depart for Chelsea.
Manchester United have been linked with a summer move for Reina and Liverpool face a battle to convince the keeper that he is best served by remaining at Anfield.
"I am not announcing my departure, far from it," he told The Guardian. "I've said lots of times I'm very happy in England and comfortable at Liverpool, but I'm not prepared to swear eternal love to anyone. That's impossible. Any player who says that is lying.
"I can't say much because I have a contract with Liverpool, but eternal love doesn't exist. No one is master of his own destiny. When a player is at a club he has to give everything - that is all you can ask of him."
It is clear that Reina wants the club's new owners, who have brought in Andy Carroll and Luis Suarez, to continue to invest in the team.
"I would never say 'I'm never going,' because even I don't know that," Reina said. "It depends on how this season finishes, on how competitive we can be.
"It depends, above all, on the ambition of the owners in building a better team - hopefully they will be generous in their efforts, but we know the economic reality."
