Arsenal boss Unai Emery shrugged off a strop from Pierre-Emerick Aubameyang after victory at Newcastle United.

Aubameyang was clearly annoyed at being substituted.

"It's normal," said Emery. "I want the players when I change the team or when I decide them not to start them in the first XI to be angry and have ambition to play and help the team and stay on the pitch. For me it's a normal situation."

On Aaron Ramsey also being substituted, the manager added: "It's also normal. He played with the national team two matches and then he played 80 minutes with us, so he asked us to change him. It's not a big problem but he was tired. I think it is no problem."
