The defender who also confirmed his retirement from international football says Les Blues triumph was harder to take than missing out on the tournament.
Koscielny was poised to be one of France’s senior players to the World Cup before he suffered an Achilles injury late last season. The injury ruled him out of the World Cup in Russia which France eventually won.
And it is that win more than his injury that the Arsenal man is finding difficult to get over.
Speaking to Canal+ Koscielny said: “The World Cup will remain a dark spot of my career.
“The injury was hard to accept. The result was even harder because they won the World Cup. I have a selfish side. I tell myself that I could have been part of the adventure and won the Cup. And I would have it in a corner of my head for the rest my life. It’s difficult and no one can put themself in my shoes.
“I was really happy for them, but also disgusted. You can not feel like a world champion, as the 60 million French could. It’s a strange feeling that during the tournament I wanted them to qualify, but at the same time I wanted them to lose. That was my feeling at the time.”
“It’s my first big injury, mentally you’re getting very strong, you’re learning a lot about football and life. I’ve worked every day at St-Raphael, and put my family aside,” he said.
“These are things in life, and you have to face all of that, during my rehabilitation, I was selfish, I only thought of myself, and I did not pay attention to my family.”
The centre back isn’t happy with a few persons, France coach Didier Deschamps being one of them.
“Deschamps called me once [since the World Cup], during my birthday in September,” Koscielny added.
“Lot of people disappointed me, and there are lots of other coaches. It feels like a slap on the face.”
“I think I gave what I could give to the French team.The national team has a very good generation with great players.
“My injury has not changed my decision: for the Blues it’s over for me. But I remain a supporter of the French team.”
“I have a new state of mind, there was the Laurent before, and the Laurent after. I want to continue to Arsenal, and come back quickly, I do not know what level I can have. but I want to fight. “
