If I was a close pal with him, I'd say " Yo Mate, this is the biggest club in the world you've got to take your chances and not snooze. You've already won it all with Bayern Munich, if think it's time you try new experiences and go explore out side.
There's every possiblity Real Madrid would win both the Champions League and Domestic La Liga games if he moves down that ends. Why the delays and too much wait? He should make his decision at the ned of the season anyways.
Real Madrid also have to invest in the right fullback position. Dani Carvajal needs to leave next season, they should look into signing a much younger player for that role. No longer Recce James who's injury prone.
