Pep Guardiola is one of a number of coaches and teammates to praise Toni Kroos during his recent documentary.
The Catalan coach worked with the midfielder at Bayern Munich before he moved on to Real Madrid in the summer of 2014.
"Toni is a very intelligent, very brainy and very calm player," Guardiola said.
"Many times, when things go badly, we tend to blame the players that seem calmer or more technical. But these players are the bravest, the ones that have the most courage.
"The players that shout the most are those that hide when things go badly. Toni is the opposite, he's the bravest of them all in the most difficult moments."
Zinedine Zidane is Kroos' current boss at Los Blancos and he wasn't shy in showing his admiration for the player.
"I love to watch Toni train," Zidane said.
"I love to be there for his training sessions. They're exceptional sessions. I'm not saying it for the sake of it. It's true.
"I've never seen him lose the ball. Well, maybe once. His game is always elegant and efficient. He never has a bad day.
"He loves football and always wants to play. I think it's something that unites us. He loves football. For me, playing is the main thing. Winning, yes, but playing is the main thing and it's like that for both of us."
Kroos has formed part of a hugely successful midfield at Real Madrid with Casemiro and Luka Modric and both players had their say on their teammate.
"Real Madrid matches always go in Kroos' rhythm," Casemiro said.
"He's one of the most important players at the club because he manages the ball and the rhythm with which we play.
"If Toni wants to play slowly, we play slowly. If he wants us to play quicker, we play quicker. We play in Kroos' way."
Meanwhile, Ballon d'Or winner Modric further added to the praise of the German.
"At Real Madrid, you're not allowed to be less than good and Kroos is an exceptional player, he looks like he's playing in slow motion," Modric said.
President Florentino Perez signed Kroos for Real Madrid and holds him amongst his very best arrivals.
"Santiago Bernabeu told us that the best players in the world have to play here," Perez said.
"That's why I signed Zidane, Ronaldo, [David] Beckham, Cristiano Ronaldo, Kroos...
"Signing the best tells the rest of the world that the best players in each position are going to play here.
"Kroos has a style that makes people want to go to a stadium to watch him. For me, he's been one of those players that was born to play for Real Madrid."
