Alexandre Lacazette has explained what his trademark ‘trumpet’ celebration is about, after showing it off again at the Emirates on Monday.

Lacazette scored two goals against West Bromwich Albion, one in each half. And after the first went in he raced over to the Arsenal fans and performed the celebration in front of them. Supporters at the Emirates have had the chance to see it in every home match in the league so far.

Some have wondered what it all means, but the 26-year-old explains that it was just an inside joke between him and his friend, saying on Arsenal Player: “It was based on a bet with a friend of mine who really likes music that involves trumpets,” reports the Daily Star.

“It was a joke between the two of us. That’s how it all started, it was all a bet. I’ve just kept doing it and I really like it. The first time was in a friendly: Lyon against Sporting Lisbon, I believe, and then I did it in the league at Nancy.”

Lacazette isn’t the only one to perform a trademark celebration for the benefit of friends and family watching at home. Mesut Özil’s celebration is to make an ‘M’ with one hand and suck his thumb with the other, because his niece’s name is ‘Mira’ and he says he wants to show her how much he loves her.

Olivier Giroud and Aaron Ramsey have both done celebrations for their newborn children in the past, as have many others in the Arsenal team. It seems like a lot of players take the opportunity to send a message to people they’re close to. With any luck, Lacazette will have many more chances to do the same again.
