Alexandre Lacazette is the most expensive signing in Arsenal’s history.

And the 26-year-old French star (who has 11 caps for his country, and one goal) began his Arsenal career in style, coming off the bench against the big guns of Sydney FC and knocking home a tap-in to open his account for the Gunners.

The reaction on social media was instantaneous, with none other than Antoine Griezmann leading the praise.

And the Arsenal fans struggled to cope with the excitement of seeing their big hope find the back of the net at the first time of asking.

But not everyone was impressed.

One fan lampooned the simplicity of Lacazette’s goal, while another claimed that the new forward isn’t fit to lace the boots of the Premier League’s best.

How did Arsenal fans respond?

By coming up with a unique chant for their new signing (that doesn’t really scan).

These are heady days for Arsenal fans.
