Unai Emerys players have plenty of time on their hands ahead of the sides clash with Leicester on Monday night and Lacazette was even practicing his celebrations in advance at London Colney.
The Frenchman has had a scintillating start to the campaign, scoring five goals in ten appearances, so its no surprise that hes brimming with confidence before the match.
However, Crouch took Lacazette down a peg or two in brilliant fashion after the strikers antics were uploaded by Arsenals official Twitter account.
My lawyers will be in touch, the former England man replied.
The Stoke City striker, who has also played for the likes of Liverpool, Tottenham and Portsmouth, made the celebration his own back when he was at the peak of his powers.

Lacazette insists there is no competition between him and Pierre-Emerick Aubameyang over who will score the most goals this term.
If Auba scores 40 goals and we get Champions league and as well we win something I will be happy, he told Sky Sports ahead of Arsenals match with Leicester.
This season we just want to win something.
There is no competition like wholl score more goals on the weekend or something like that.
Maybe in training because its better to improve but not on the weekend.
