He has cited press victimisation as one of the factors behind his thinking and appears keen to move, and added further to that today.
Speaking to Marca he said: "First I have a contract with the club, but if one day I want to sign (for another club), Liverpool will hear the offer, as it does with other players.
"They must agree with other teams, but the word of the player, in this case mine, is important. If you need a change, you should listen to the player.
"Every player aspires (to be the best) and if you ask a child of eight years they would say one day they would go to Real Madrid or Barcelona."
