New Arsenal signing Pierre Emerick-Aubameyang took to social media to express his reaction following his first game after moving to the Emirates stadium.

Arsene Wenger decided to let go of want-away forward Alexis Sanchez just over a week before the January transfer window was brought to an end.

And shortly after the exit of the Chilean international, the Gunners confirmed the marquee signing of Pierre Emerick-Aubameyang from Borussia Dortmund in a club-record deal.

The 28-year-old did not take too long to get off the mark for his new club as he scored in the first half of the 5-1 victory over Everton on Saturday.

And after his debut in Arsenal colours, Aubameyang was quick to express his delight to the fans through a post on Instagram.
