​Borussia Dortmund midfielder Shinji Kagawa has sent Twitter into meltdown, after posting a hilarious video depicting himself and three of his teammates charging about in incredible scenes of ninja action.

Posting on his ​official Twitter page, Kagawa - alongside teammates Michy Batshuayi, Sokratis Papastathopoulos, and Marco Reus - can be seen shimmying around a vivid Japanese landscape, hurling balls of light into the air, building human towers and even adorning a house with ribbons. The NinjaMe app is intended as a fun way to send birthday messages.

Kagawa is known for his enjoyment of the lighter side of the game, having seen another of his online posts go viral in 2017 - in which he mercilessly nutmegged a child to the extent that the youngster broke down in tears. This sparked a brief online craze of footballers outselling children on social media, ​with Raheem Sterling among those outwitting juveniles with his skills.

With Chelsea's notorious purveyor of online banter Batshuayi on loan to the ​Bundesliga side until the end of the season, there's no end to the potential mischief the pair could create. On the pitch, ​BVB were made to work hard to beat Köln on Friday night, but a Batshuayi brace and André Schurle's late winner earned a 3-2 win for Die Borussen Die Schwarzgelben.

In other news, Pierre Emerick-Aubameyang enjoyed a fine debut for ​Arsenal after leaving ​Dortmund for a fee believed to be in the region of £57m. The Gabonese international scored a delightful chip in his side's 5-1 thrashing of ​Everton at the Emirates Stadium, despite replays showing that the tenacious forward was at least a yard offside when he netted the goal.
