Following a suspension to Pierre-Emerick Aubameyang, Mikel Arteta has sent a warning to Arsenal forwards urging them to step up in the skipper's absence.
The Gabonese will now miss the upcoming matches against Sheffield United, Chelsea and the FA Cup fourth-round tie against Bournemouth, leaving Arteta with a major selection headache.
Lacazette is currently enduring a six-game goal drought with Arteta admitting he is tweaking his position, "You can help [Lacazette find his goalscoring form] by talking to him and giving him confidence, but that ball has to end up in the net.
"I think that’s the best medicine for strikers. What we have to try to do is put Laca in positions where he can have as many opportunities to do that as possible during a game."
Arteta also urged Arsenal forwards to step up in Aubameyang's absence, "You know, when one of your big players is not there, they have to take responsibility.
"I’m sure when they’re not playing, they want a chance and they talk. It’s time to talk on the pitch, not outside.
"You come on there, you make the impact that he made and you sure me that you are as good as him or even better. You have the chance. [Gabriel Martinelli] is having an impact every time he’s coming on, but it’s not just him.
"It’s other players like Reiss and Nico too, so whoever players there on Saturday has to step in and has to be thinking that they need to make the difference for the team."
