"It truly has been an honor to share the Real Madrid midfield with you. You have qualities that make you a unique and special footballer, and there will never be another Toni Kroos. Unforgettable European nights, titles, the magic of the Bernabéu... We will never forget this golden era at the club of our lives. You have achieved everything but you still have one left. Together for 15. I'll miss you, friend."
