Allegedly he's taking a significant paycut to join Madrid. Still among the top paid in the world, mind. Just not as exorbitantly so.
He should have moved at the last juncture. He's pure brilliance but also needs to get moving if he wants to leave the legacy he seems to aspire to, to be an all time great rather than one of the best of his time.
He's got the toolbox to do it. Whether he will is a different question.
