GIF: Two-footed horror tackle not enough to warrant a yellow card from referee

How on Earth did this deplorable tackle go unpunished.

It seems inappropriate to refer to the match between France and Belgium over the weekend as a friendly, after seeing what transpired on the pitch. The lowest point of the match may have come in the 27th minute when Belgian winger Dries Mertens was the victim of a horrendous challenge from Benoît Trémoulinas. The Frenchman violently launched himself towards Mertins with both feet forward, sending him crashing down to the turf writhing in agony. Despite appearing to be a nailed on red card offence, the French left back received no warning for the incident. Fortunately though, Mertins was able to resume playing the match after receiving treatment for about a minute. Hat-tip to Reddit
