Arsene Wenger has not decided whether he will start Alexandre Lacazette against CSKA Moscow on Thursday night - but is confident we will see the best of him when he does play.
The France international spent nearly two months out with a knee injury, and the boss says all the signs since his return to training have been positive.
"It's good to have him back because it gives us different opportunities," Wenger said. "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."
