Arsenal are facing the prospect of losing Mohamed Elneny for the rest of the season.

The Gunners could be without the Egyptian midfielder after he sustained a knee injury.

The club are close to completing the signing of Jorginho from Chelsea, per Fabrizio Romano and other sources.

A statement from the club read: "Mo has had successful surgery in London and will be ruled out for an extended period of time.

"A more detailed timescale will be established once the early stages of rehabilitation have been completed.

"Everyone at the club will be offering Mo all the support he needs and working hard with him so he can return to action as soon as possible."
