Lacazette found the net on Saturday during Arsenal’s 2-0 win at Wolves as he scored for the first time since March.
The Frenchman has endured a difficult season this term and he has scored only 10 times during the current campaign.
Lacazette, however, is still attracting interest from abroad, namely Atletico Madrid, and Arteta is keen to hold talks with him about his future.
The striker has two years to run on his current contract and Arsenal’s preferred policy is to resolve players’ futures before they enter the final 12 months on their deals.
“We have to have a chat about the next step with him and get his idea, his feeling,” said Arteta. “As I said, I am really happy with him. He is a player that I always liked, even when I wasn’t here, because of what he brings to the team - his qualities, his abilities, his work-rate.
“So, let’s see. But now we are in a crucial moment, there is no time to talk about a lot of contractual situations. We still have time and we will do it in the right moment.”
Arsenal’s win over Wolves on Saturday was their third in a row in the Premier League and they still have an outside chance of qualifying for the Champions League.
If Manchester City’s ban from Europe is upheld, a fifth-place finish could be good enough and Arsenal are currently six points off Manchester United - who occupy that spot.
“I think we have to win every game and then wait and pray,” said Arteta.“We need to go game by game. A few weeks ago we were really far, even thinking about Europe as well.
“We are a little bit closer at the moment so let’s go game by game and see where it takes us. We are in a good run and we have some momentum. We are at a crucial point in the season where we are going to face the top teams in the next two weeks.
“We just try to get prepared as much as we can. We know how important these games are going to be for the future of the season. We are very focused and committed to try to do as well as we can.”
