Turkey moved top their European Championship qualifying group by dominating World Cup winners France in a 2-0 home victory Saturday.
Turkey have nine points from three wins and have yet to concede a goal in Group H. France had scored four goals in each of their first two wins, but this time their attack was kept quiet by Turkey's solid defence while the French defence was too easily breached.
France coach Didier Deschamps was scathing about his side's performance in Konya.
"When you play like that on a collective level there's nothing positive to take from the game," he told broadcaster TF1. "We didn't play the way we should have against a team which played the way it likes to."
After right-back Benjamin Pavard gave away a free kick on the left in the 30th minute, attacking midfielder Cengiz Under whipped the ball to the back post, where it was headed back across goal for defender Kaan Ayhan to nod powerfully past goalkeeper Hugo Lloris.
The highly rated 21-year-old Under, who has caught the eye several times with Roma in Serie A, put Turkey further ahead 10 minutes later with a fine finish.
France was badly at fault, though, as Barcelona centre-back Samuel Umtiti and Manchester United midfielder Paul Pogba both lost the ball in clumsy fashion and in quick succession.
Central midfielder Dorukhan Tokoz picked it up and attacked the panicky, retreating defence. He fed a pass to Under breaking into the right side of the penalty area, and Under confidently smacked a low shot into the bottom left corner.
"We weren't present [and] that's what the highest level is all about, whether you're world champions or not," Deschamps said. "When you don't show the right intentions you can't hope for anything."
On Tuesday, Turkey are away to third-place Iceland while France look to bounce back at last-place Andorra.
Iceland and France each have six points.
