Havertz posts on Twitter after scoring brace in Arsenal's 5-0 win v Chelsea

Arsenal routed Chelsea 5-0. Perhaps the most heart-breaking part of this painful defeat was seeing Kai Havertz bag a brace.

The German celebrated the first goal by knee-sliding towards the corner flag. There was no sign of restraint in his celebration after scoring against his former club.

"Important 3 points and performance to continue the momentum!" he tweeted after the game, adding a picture of his knee-slide celebration.

Chelsea sold Havertz to Arsenal last summer for £65m.
