Antonio Rudiger says he thought there was something wrong with N'Golo Kante because the Chelsea midfielder talks in clicks.
Kante, who joined Chelsea from Leicester in 2016, has been hailed by many as one of the nicest figures in football.
Rudiger says the rumours are true as he spoke of the humble nature of the France international.

What did Rudiger say about Kante?
Writing in The Player's Tribune, Rudiger said: "I have to tell a quick story about one of the nicest guys in football. I am speaking, of course, about N’Golo Kante.
"Before I came to Chelsea, I had heard all the beautiful stories about him. They said he is always smiling. They said he still drives an old Mini Cooper. They said he never raises his voice. But you know how it goes in football, right? No one is really like that. There is too much pressure, too much disappointment. We are all human. No one is that cool all the time. It’s impossible.
"Then I met N’Golo.
"Everything I said to this guy, he would just look at me and nod his head, like he thought everything I said was really interesting. And he would do this thing … I don’t really know how to explain it on paper. You have to hear it. Every time I’m talking, he would go *click, click, click* with his mouth.
"'Hey NG, do you want to go get some food?'
"NG, when you press him…
"'Click, clock, click.'
"Man, I literally thought there was something wrong with him. One day, I finally asked him: 'NG, why do you talk like that? What’s going on with you, brother?'
"He said: 'Sorry?'
"I said: 'The clicks, bro! What’s wrong with you?'
"He was smiling. He said: 'Ahhh, it’s just my neighborhood.'
"See, in the banlieue where he grew up in Paris, they always make this sound. It’s like slang for 'yes'. I don’t know how it started, but that’s what they do there.
"It’s like saying: 'Yeah, yeah, O.K., cool.' And I thought it was so funny, because I’m from a similar type of neighborhood in Germany, but I’d never heard anything like that in my life. The whole time, I thought he was messing with me!"
Rudiger on 'humble' Kante
The German defender, who will leave Chelsea for Real Madrid this summer, believes Kante takes being humble to a whole new level, citing his devotion to his Mini Cooper car as an example.
"Everything with NG is authentic. Even the Mini Cooper — people laugh about it, but there is a real story behind it," he said.
"It was a dream for NG to make it to the Premier League, coming from where he came from, and the Mini was the first car that he bought when he got to England. So for him, it is not just a car. It has a deep meaning.
"Of course, the boys always joke with him about it, but I am telling you — this man is so polite that he just tells you what you want to hear.
"Someone will say: 'NG, you know what car is really cool? A Mercedes, bro. I can see you whippin’ a black Mercedes'.
"And NG will just look at them genuinely and say: 'Yes, O.K. We will think about it. Thank you, that’s a good idea.'
"But he’s just playing with you! At the end of the day, you know that you’re going to be seeing that Mini at the training ground for the next 10 years.
"I tell people all the time, there is humble. And there is humble. And then there is NG."
