Alexandre Lacazette has really hit the ground running at Arsenal this season.

Traditionally, the Premier League can be an unforgiving place for new strikers who have arrived from abroad with a big reputation - yes, we're looking at you Andriy Shevchenko.

Not for Lacazette, though, who has taken no time at all to adapt to the rigours of the top division in English football after joining the Gunners from Arsenal for a fee believed to be in the region of £50 million.

The 26-year-old wouldn't have been the first to take some time to adjust to his new surroundings but four goals from his opening six games in an Arsenal shirt is a more than respectable return.

Of course, two of those came last night when as he inspired Arsene Wenger's men to an important 2-0 victory over West Brom at the Emirates.

The first a header into an open goal after Alexis Sanchez's free-kick was tipped onto the bar. His second came from the penalty spot after Aaron Ramsey was fouled by Allan Nyom inside the box.

The brace also meant Gunners fans got to see his the French international perform his trademark celebration.

So it might not be as exciting as a couple of cartwheels or front flips but Lacazette always does the same thing: bring his right hand towards his mouth and outstretch the other arm so it points in the same direction.

Just like this:

And the ex-Lyon star has revealed the inspiration behind his celebrated is actually the result of a bet he made.

"It was based on a bet with a friend of mine who really likes music that involves trumpets," he told the Arsenal website.

"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."

Whatever works for you!

Arsenal fans won't care one bit how he came up with it as long as they keep seeing it this season.

After the win vs West Brom, Wenger's side travel to BATE Borisov on Thursday before another home clash against Brighton on Sunday in a hectic week for the north London club.
