Villa earned the points with an injury-time winner struck by Emi Buendia.
“We are of course disappointed with the result,” Gyokeres told arsenal.com. “It's not a great feeling right now, but it's only December and there are a lot of games to play.
“You can always find some positives, but it's still a very difficult way to lose a football game. It's tough right now, but we'll look forward to the next one soon.”
He added, “We have to keep creating chances and get shots on goal because then you'll eventually score more goals. So yes, that's of course a positive and we just need to do things in between also a bit better.
“It's football. If you score in the last few seconds or minutes, that is an unbelievable feeling, so it goes both ways. Today, unfortunately, it was the other way. It's tough, but you learn from it.
“If we focus on what we can control and do in our favour and focus on the next game, we'll be better, I think.”
