Walcott squandered chances at Sunderland on Saturday but was deadly in France - and he wants much more of that.
"The cross came in and the full back missed it," Walcott told Arsenal Player. "It felt like the ball was in the air for a decade and I managed to keep my eye on it and [it was] pure technique into the top corner.
"It meant a lot getting off the mark [for the season]. Hopefully there are going to be more to come now. I started pretty late last year and I finished as top goalscorer so it's a good sign. I'm pretty sure of that."
