Real Madrid defender Raphael Varane lauded coach Zinedine Zidane for never allowing him to get into his comfort zone.
Varane, 24, signed a new deal with the LaLiga and European champions last week, extending his contract until 2022.
"He has given me a lot, in my attitude, in my play and in the risks that I take," Varane said, via Marca.
"He is someone that doesn't allow me to remain in my comfort zone, he has a lot of experience and it is a great opportunity for me to learn from him."
The centre-back believes he will only get better, saying: "I have my style of play and people can criticise me for that which is not a problem.
"I try to play to my strengths and I think I am a more rounded player now aged 24 than I was aged 18.
"In my position you talk about a mature player being around 28 and it is normal that you improve."
