Oleks Zinchenko was left delighted after Arsenal's 3-0 win at Bournemouth.
Two goals from Martin Odegaard within the opening 11 minutes put Arsenal on course for a third straight win, with William Saliba adding a third just after half-time to maintain their 100% record this term.
Zinchenko said, “It's a great feeling to get three points and we don't concede a goal.
“It's always important to score in the beginning of the game because this first goal can give you some confidence to control the game and that's what we did. We did well, especially in the first half, the opponent didn't create anything - they had zero shots on target.
“In the second half they started to play with three at the back and we were suffering at some points, but in the end we didn't concede, that's the most important thing. There are still a lot of things to improve, but I think we are on the right way."
He added: “There's a lot of games ahead of us, there's a lot of things to improve, but we just need to be focused on the next one, the next one, the next one.
“We need to analyse what we have done well, what we should improve, what we should change and we know the manager is going to tell us. We need to show our best performance every single week."
