Iker Casillas has interest in one day playing in the MLS.

"I have no problem of saying that I would like to play in the U.S.," Casillas told The Wall Street Journal, although he didn't indicate any timetable for his departure. "This has been a tough past year and a half, but it has made me tougher mentally."

Casillas is signed at Real Madrid through 2017.

"At the club level, Real Madrid winning lifted a huge burden," he told WSJ. "We'd been 12 years without winning [Champions League] and we're lucky that we've won many titles recently when there had been 30 or so years when Real Madrid hadn't won. That took the pressure off us and helped us move forward."
