Legendary Real Madrid goalkeeper Iker Casillas has revealed that he harbours ambitions to one day embark on an "adventure" in MLS.
Casillas's existing contract expires in 2017, but speculation is rife that the European champions could replace him with Manchester United's David de Gea in the summer.
The 33-year-old, who joined the club at the age of nine, told the Wall Street Journal: "I have no problem of saying that I would like to play in the US.
"I would be unable to leave Real Madrid and join a competing team but I could leave to have an adventure, maybe not at that level in Europe, but innovative and different in a growing league like MLS.
"I would like to experience a different kind of football and put into perspective all the time I've been at Real Madrid."
Casillas, who made his senior debut as a 17-year-old back in 1999, has since notched over 700 appearances for the Blancos.
