The Wales international also expressed his delight at scoring the winning goal against what he believes is a "very strong" team.
"I'm enjoying myself at the moment and everything seems to be going in. I'm delighted with the way I'm playing and the goals I'm scoring but it was a great team effort and we are delighted with that," The Mirror quotes him as saying.
"It was a proper away performance, defending well and going on the counterattack. They are no mugs, they got the final last year and were unlucky, they are a very strong team and we had to do our defensive work really well. We're delighted with that."
The result moves Arsenal to the top of Group F with nine points from four matches.
