The fact that he had to go back and look at it again after he'd already left the screen proves that he wasn't sure. It wasn't clear. And if it's not clear, you can't give it.
Dude, your country just won the World Cup and you are here arguing on a forum. Get out and celebrate!Following the balls with eyes, conveniently opening the hand at the right time, keeping it steady* while deflecting the ball. At this point, we shouldn't care if a witness pretends that his arm is not connected to his brain.
He's not a bad guy, he doesn't want the ball to pass at any cost and just made a bad 300 ms decision.
As for the referee hesitation, that's pure speculation after seeing him getting back to the monitor (he was likely been said in the earphone that he left the monitor before seing the forth-and-back slow motion sequence, since he clearly missed that part).
*: from an other angle, it even look more like a punch than a steady hand.
Kante did look bad in the final. He could have won best player instead of Modric with a better performance yesterday. That's likely why.
I'm pleased that the Player Of The Tournament award didn't automatically go to a forward like every World Player Of The Year since 2007.
Forwards get disproportionate amounts of evaluative praise and regard.
