The Swedish star scored an incredibly lucky free-kick in the first half of the game, with his low shot hitting a Saint-Étienne defender and crawling over the line.
Both defenders and goalkeeper were unable to react as they watched the ball roll over the line almost as if it was in slow motion.
His second goal came in the second-half, a tap in from about two yards after the ball fell at his feet with the goalkeeper not in sight.
The forward then made it three from the penalty spot, tucking it into the bottom corner with ease after the goalkeeper dived the wrong way.
No doubt, it will be one of the easiest hat-tricks and least skilful he will ever score!
No doubt that the state of Zlatan’s hat-trick was going to go unnoticed.
Twitter took note of just how lucky and easy of a triple that was.
Probably Zlatan's luckiest Hat-trick ever.

Too easy for Zlatan
Zlatan needs to find another sport because this football lark seems far too easy for him.
