When a player joins the first-team squad, it is a long-held tradition that they must sing an initiation song in front of their new team-mates.
Mesut Ozil has seen a lot of them during his four years at the club, and says Petr Cech’s effort was the most memorable of all.
“Honestly, Petr fascinated me once,” Ozil told Arsenal Player. “You know as a young or new player, you have to stand in front of the team. When it was Petr’s turn, he just started to rap about all of us and the training staff.
“Everyone was shocked because of how good it was. In terms of the best voice, I’d go with Shkodran Mustafi. He sang a Justin Bieber song, I don’t know which one, but it wasn’t bad.
“I sang something which nobody could understand. You have to get up in front of the team and they’re cheering you, but they don’t know what you’re singing. Even if you were having a go at them, they’d still celebrate you!”
