Liverpool goalkeeper Pepe Reina has refused to rule out a summer move to bitter Premier League rivals Manchester United.
United are considering their goalkeeping options as they seek a replacement for Edwin van der Sar when the Dutchman retires at the end of the season.
Reina has been mooted as a possible transfer target after establishing himself as one of the best goalkeepers in Europe during his time at Liverpool.
He told Spanish radio station Ondo Sera: "Yes, well van der Sar will hang up his gloves in the summer so of course they are looking. I can't do anything. I can't say anything logically as I have a contract with Liverpool.
"Of course one likes to fight for titles and be in a team that does that. We always fought to be in the Champions League and try to win the title. But unfortunately it hasn't been the case in the last couple of years."
Former Barcelona and Villarreal custodian Reina has left the door open to quit Anfield if they fail to qualify for the Champions League.
He added: "I won't lie, I want to play in the Champions League and challenge for titles."
