The Croatian took a trip down memory lane as he shared a series of photographs of himself along with the German on the pitch and in the caption he wrote, "Dear Toni, It is difficult for me to write these words. The world of football is sad because a historic footballer is leaving, and I admit that I am also very sad. Friend, you are a legend of this sport and a legend of Real Madrid. I have really enjoyed playing alongside you.
"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."
