The French striker has been settling in well to life at Arsenal after having signed for the Gunners from Lyon in the summer transfer window last year.
Lacazette recently made his return to the first team for the Gunners after having undergone knee surgery to correct a long-standing problem back in February.
The striker will now be hoping to play a regular starting role in the Arsenal first team this season as he bids to try and help the north London side end the season on a high.
And Wenger has revealed that Lacazette seems like a different player in training since having undergone his successful surgery.
Speaking at a news conference before Arsenal’s clash with CSKA Moscow, Wenger said on Wednesday: “It’s good to have him back because it gives us different opportunities.
“Danny [Welbeck] is more a guy who goes behind, whereas Lacazette is more combination play so to have both options is important.
“I think [we will see the best of him] because I realise now when I see him in training that he was not himself for a while.
“It was not dramatically different before. He was a good player. But I think in the last seven or eight games he played, he was not completely free with his knee.
“Unfortunately, in our job you need you body and when you are not 100 per cent you cannot play well.”
Arsenal now switch their attentions back to Premier League affairs and their home clash against Southampton in the Premier League on Sunday.
The Gunners are currently in sixth place in the Premier League table as they bid to try and finish as highly as possible in the top flight.
