Luka Modric and Toni Kroos, the M and K of Real Madrid's legendary midfield, bid farewell to the C, Casemiro who signed with Manchester United, their faithful partner in the game and titles. And they do it with exclusive and emotional letters in which they say goodbye to their friend after seven seasons together.

Kroos

"With you, my dear Case, it was impossible not to break a sweat... in any situation. Because you wouldn't let us relax even in the Turkish bath. Staying there was another torment: you told someone to go there and you almost had exercise bikes and weights ready there – that's a little heads-up for your new colleagues. Because with you, even the Turkish bath was a gym... and you only allowed people to lie down when it was time to do sit-ups.

"I'm going to miss you. As an exemplary professional. As a top player. As a fighter who saved me from trouble... But, above all, as a good person.

"We've made history, man! What a legendary era...

"Now our sports paths separate, but our friendship remains. I assure you.

"I wish you the best, see you soon.

"Good luck.

"Your Toni."

Modric

"Dear Case, I still remember your debut with our club... How nervous you were! I asked you to be calm and now I think about it and see how it turned out. What you have achieved! It was also my first season and neither of us could imagine what football had in store for us.

"You have become a true leader. You have always been there for your teammates and for Real Madrid. We will always remember it.

"We have won a lot together, but I keep the moments that nobody sees. With the day-to-day work in Valdebebas. And especially with the jokes, because you have always been in a good mood, even in moments of tension or when there were failures.

"Those laughs with you gave me peace of mind. Just like looking back and seeing you, knowing there's going to be a lot of 'Njega-Njega.' You have been the best bodyguard in the world."
