Remember when the world recoiled in horror as Nigel de Jong thrusted his boot into the chest of Xabi Alonso in the 2010 World Cup final?Well, that disgraceful tackle - which somehow only merited a yellow card - now looks tame thanks to Schalke goalkeeper, Alexander Nubel.The German was shown one of the most deserved red cards in the history of football yesterday against Eintracht Frankfurt.Nubel flew off his line in the 66th minute and aimed a cowardly 'karate kick' right into the chest of Frankfurt playmaker Mijat Gacinovic.Bundesliga referee Felix Zwayer quickly brandished a red card and frankly, Nubel needs to be punished even more severely in the coming days.

You can watch the incident below.

What on earth was he thinking?! He was lucky that Gacinovic was only left with surface wounds, with the Serbian revealing the extent of the damage on social media after the game.

Users on Twitter were not happy with Nubel's challenge, with some correctly pointing out that outside of a football pitch, the German would probably have been charged with assault.

Schalke went on to win the game despite Nubel's sending off, with former Chelsea left-back Baba Rahman scoring the only goal of the game in the 53rd minute.

But the fixture was completely overshadowed by the red card, with Gacinovic having to be replaced by Goncalo Paciencia after the incident.

You'll be hard pushed to find a worse tackle in 2019/20 and Nubel is lucky not to have caused serious harm to a fellow professional.
