Wenger has no doubts his team are now maturing at the right time.
He told arsenal.com: "I am convinced, yes. I have problems convincing you but that is normal! It is the start of the season and I think it is important that we take encouragement from what we are doing at the moment and we keep feet on the ground and a good concentration.
"You watched the game tonight. You don't need replays to see that we can be very creative, be dangerous, score goals. You see the pace we can play at and the number of chances we can create. This team knocked Sevilla out, they're a good side, Braga."
