Arsenal is seventh in the Premier League after 33 rounds, three points adrift of sixth-placed Wolves and nine behind Leicester – who are third.
Lacazette is contracted to Arsenal until 2022 after arriving from Ligue 1 outfit Lyon in 2017.
Lacazette has only started two of Arsenal’s last eight Premier League fixtures and Arteta acknowledged the Frenchman’s future has to be resolved.
The 29-year-old came off the bench and scored in Arsenal’s 2-0 Premier League win over high-flying Wolves on Saturday.
“We have to have a chat about the next step with him and get his ideas and his feelings. As I said, I am really happy with him,” said Arteta, whose Arsenal face Leicester City on Tuesday.
“He’s a player that I’ve always liked, even when I wasn’t here, because of what he brings to the team: his qualities, his ability, his work rate. So let’s see.
“Now we are in a crucial moment. It’s no time to talk about a lot of contract situations. We still have time and we will do it at the right moment.”
The Gunners are in the midst of a four-game unbeaten streak, having also reached the FA Cup semi-finals.
