The French striker had been out of action since picking up a knee injury against Tottenham on 10 February but he came off the bench to score Arsenal’s third goal from the penalty spot in their 3-0 win over Stoke in the top flight on Sunday.
Lacazette will now be hoping to play an important part in the Arsenal side between now and the end of the season as they look to try and end the campaign on a high.
Arsenal return to Europa League acton on Thursday night with the first leg of their crunch quarter-final showdown against CSKA Moscow.
And Wenger is hoping to see the striker regain full fitness as quickly as possible following his return to action at the weekend.
Speaking at his post-match news conference on Sunday, Wenger said: “He’s still lacking a bit of competitive edge.
“He’s been out for two months, he worked hard, but he still lacks a fraction maybe. In training, he looks sharp.
“How long can he last in a game? I don’t know. He certainly needs one or two more games.”
Lacazette has been settling in well to life at Arsenal following his move to the north London club from Lyon in the summer transfer window last season.
The 26-year-old has scored 10 goals and made three assists in 27 Premier League games for the Gunners so far.
