Unai Emery believes the ankle injury sustained by Alexandre Lacazette in Sunday's Emirates Cup defeat to Lyon is "not serious".

Arsenal went down 2-1 at home to the Ligue 1 side despite taking the lead through Pierre-Emerick Aubameyang, with Moussa Dembele getting both of the visitors' goals.

Prior to the first goal, Arsenal lost former Lyon star Lacazette to an ankle injury in the 13th minute following an early knock.

Although he showed little sign of pain when jogging off the pitch, Lacazette was seen wearing a protective boot on his left foot post-game and was walking with a notable limp.

The striker will be examined by medical staff in the coming days, but Emery is confident Lacazette will not need long to rest.

"The doctor said to me he's going to check tomorrow [Monday]," Emery said. "It's in his ankle."He's going to be assessed over the next few days – it's not serious."
