Wilshere out for three months

The England international was substituted during the second half of Saturday's defeat to Manchester United after damaging ankle ligaments and was subsequently sent to a specialist to be assessed.

Wilshere has now gone under the knife and is likely to be out of action until February.

An Arsenal statement read: "Jack Wilshere has had successful surgery on his left ankle and will be out for approximately three months.

"An assessment with a specialist confirmed the need for an operation and the 22-year-old had successful surgery to his ankle in London on Thursday afternoon."
