Arsenal manager Unai Emery has played down concerns over Alexandre Lacazette's injury suffered during Sunday's 2-1 loss to Lyon.

Pierre-Emerick Aubameyang's opener for the Gunners was cancelled out by two goals to Moussa Dembele to give the visitors a welcome preseason win.

Lacazette, who limped off after 12 minutes, was pictured after the game in a protective boot, but Emery says the ankle injury is not serious.

"The doctor said to me he's going to check tomorrow," Emery said in his post-game press conference.

"It's in his ankle. He's going to be assessed over the next few days – it's not serious."
