Liverpool fullback Alvaro Arbeloa cannot rule out a move to Real Madrid.
"I am happy at Liverpool, but I have something to prove in Spain as I did not show my best form in La Liga," he told El Mundo. "One day, I'm sure I will return.
"It is always nice to be linked to big teams - even to this Madrid side in a time of transition. They are working hard to build a great team. I have one more year remaining on my Liverpool deal, but anything can happen.
"A contract renewal is in the air. I am contracted for one more year, but if Liverpool get an offer they will consider it. It is all in the hands of my agent."
