Sead Kolasinac believes Arsenal are stronger under the management of coach Unai Emery.
The Spaniard was brought in to replace long-serving manager Arsene Wenger over the summer after the Gunners finished in sixth last season — their worst finish under Wenger.
After losing the first two games of Emery's reign, Arsenal haven't tasted defeat since the 3-2 loss against Chelsea back in August, a run that has spanned 20 games in all competitions.
And the 25-year-old has hailed the influence of the former PSG and Valencia coach, suggesting that Arsenal have become stronger since his arrival.
"When you don't lose a game for that long, the belief is there for everyone," he told Sky Sports.
"Last season we didn't have a run like this, but when you're 20 unbeaten you have lots of confidence and belief and sometimes things take care of themselves.
"We're stronger in what we're doing this year, probably.
Several Arsenal players have previously spoken about Emery's meticulous preparation for games and the Bosnian believes the squad are benefitting from his new methods.
"The manager always prepares us very well for games," he added.
"We watch a lot of video, and speaking as a full-back he and his staff will show us what we're doing well and what we need to improve, and that helps a lot when you're shown things.
"It might be that you weren't standing right in one game, make sure you stand in a better position in the next one. That means you learn from game to game and become better, and it's a key to success."
