The former Real Sociedad player has made no secret of his affection towards Liverpool having played for the Anfield club for five years.
And recent press reports suggest that current Liverpool manager Brendan Rodgers may try to tempt Alonso back to the club in the summer.
Alonso said in The People: "I haven't yet decided my future - I am signed to Real Madrid until 2014 and that is my situation."
Alonso was speaking ahead of Sunday's Liverpool versus Chelsea clash in the Premier League and it is a fixture that he looks back on fondly.
Alonso added: "Matches between Chelsea and Liverpool during Mourinho's time were always hard and very difficult to win.
"In those years Liverpool were terrific against them. We increased the level of our game.
"Tactically, those matches were battles and on the pitch there was so much intensity."
