“Unfortunately he had a little procedure this morning,” Arteta said.

“He had some discomfort in his knee that has been causing some issues and he had to go and resolve it. It’s not something major but he is going to be out for a few weeks I think.”

Jesus joined Arsenal from Manchester City last season.
