The French striker scored his second Premier League goal against Bournemouth, making the most of some free-flowing build-up play by the Gunners before powering a thunderous strike past Begovic.
Alexandre Lacazette was on the scoresheet again for Arsenal, and he did so in his side's 3-0 win over Bournemouth at the Emirates, finishing off a good move from Wenger's side.
Mesut Ozil played a forward pass for Lacazette, who got a touch ahead of Nathan Ake to find Welbeck. The Frenchman received the return pass before firing a clinical finish from the edge of the box.
