Granit Xhaka performed a song for his Arsenal team-mates as part of an age-old tradition for footballers joining a new club.
Switzerland international Xhaka joined Arsenal at the end of last season from Bundesliga side Borussia Monchengladbach for a fee in the region of £30m, before heading to France to represent his country at Euro 2016.
After being granted some extra time off after the tournament, the 23-year-old finally liked up with his new team-mates last week, ahead of Arsenal's pre-season tour to the United States, making his debut in Thursday night's 2-1 win over the MLS All-Stars in San Jose.
But that was not his first Arsenal performance - click on the video above to watch Xhaka serenade his team-mates in his native tongue.
It is fair to say that striker Joel Campbell looks like he is enjoying it, while Santi Cazorla cannot seem to take the smile off his face.
