I found this translation of his French post-race interview. Riveting.
There are not 3600 days like this in a carreer so since the beginning I see it "turned" really good in the first climb and I saw everybody panic so I channelled myself. I take on myself, I say to myself that I should be calm, I should be patient today and that I will be rapidly alone so I need to be diligent. We see Movistar try to accelerate. Astana plays really well. When I saw that Primoz Roglic was there, I say to myself : "Ok I focus on him and Valverde" but finally when we were 3 with Roglic, I say : "it's maybe too Early but go Kid, it remain 25 km, there is one minute, I need to manage and to go, you will not have regrets at the finish." No regrets, I made the most perfect race of my carreer. It's also a team work even if today I was alone because they help me all the week they protect me so a great thank you to them to protect me and to trust me this week. I know Primoz would not play the victory. At the foot of the climb he said he does not care about the stage victory so I focus on that, on my effort and I know in the last climb I had to attack to make Carthy in diffulty and in the headset I heard that Primoz will let me win and at the top of the climb he confirms me. I give it all and a great thank you to him who was a Lord today It's the most beautiful victory of my carreer, with so much good riders, in Pays Basque, in Arrate a great place of this land. The most beautiful victory on an exceptionnal day. I have legs I never had before so I'm really really happy. I need to recover for the Ardennaises and maybe there will be something to do with a good team.
