Henrikh Mkhitaryan believes Arsenal have gone to a new level under Unai Emery because the former PSG boss has built on the legacy left by previous manager Arsene Wenger.
Wenger spent more than two decades at the London club, building a powerhouse of English football along the way.
Despite his long run of success, recent failures to finish in the top four and to challenge for tittles saw the French boss leave the club at the end of last season.
His replacement, Emery, has the club sitting fifth in the league table, with a chance to close the gap on the top four to just one point with a win on Sunday against Wolves.
The Gunners trail league leaders Manchester City by just six points, and while it has yet to be seen if Emery's side can sustain their title chase, Mkhitaryan believes the work of the new boss has the club playing at a different level.
"The playing style, the playing philosophy," the midfielder said when asked what was different for the club under Emery. "Not a lot but he has just built on the base Arsene Wenger has built in 22 years.
"The players have accepted all the conditions. Everything is what Emery is expecting and asking from us."
And while the results against the league's contenders will have to improve for any title tilt to be taken seriously, Mkhitaryan feels there is a new energy around the club.
"The culture changed a bit in the club and as well outside the club," he said.
"Now people are believing more in ourselves because we are playing a bit differently, we are giving them confidence and playing the way they want us to play.
"We are scoring goals, winning games and it is the best feeling for the supporters."
