The striker scored both of the Gunners goals in their 2-0 win over West Bromwich Albion on Monday night, but he says it is the defence that is key to their current run of good form.
"There was no feeling of panic in the team," said Lacazette.
"We knew that working together would pay off. During the month of September we have reconstructed ourselves defensively. We won [against West Brom] and we won with a clean sheet."
