Arsenal striker Pierre-Emerick Aubameyang says it will be "weird" for the club to move forward after the departure of Arsene Wenger.
The Frenchman left the club after 22 years with Unai Emery taking over earlier this week.
Aubameyang joined Arsenal during last January's transfer window, expecting to work with Wenger for at least two years.
But he will now have to adapt to Emery's tactics.
"It's a very good coach, it's never easy in Paris, there's a lot of pressure," the striker told RMC Sport.
"I know he did a great job in Seville and Paris, too.
"Of course it's weird that the coach goes after 22 years.
"It's life, we have to move forward, we'll have to get everyone thinking to work hard to compete with the best."
