Jack Wilshere will undergo surgery on his fractured leg next week, Arsene Wenger revealed on Friday.

The injury-plagued Arsenal midfielder will be sidelined for at least another three months, ruling him out until Christmas, after a specialist advised that he has surgery on his fractured left fibula.

Speaking at his weekly media briefing on Friday morning Wenger confirmed that Wilshere will have surgery next week. “It is a blow, a big problem. But on the short term only because it does not damage his future.”

Wenger retains full faith in the Gunners talisman despite some off-field controversies and the series of serious injuries that have stalled his progress since his breakthrough 2010-11 campaign.

As revealed by Football Insider, Arsenal will press ahead with tying Wilshere down to a new contract despite the midfielder’s latest crushing injury blow.

Arsenal have offered the England international a £110,000-a-week contract that would lift him into the second bracket of earners at Emirates Stadium, behind Mesut Ozil and Alexis Sanchez but alongside Aaron Ramsey and Theo Walcott, who recently signed a new four-year contract.

Wilshere’s camp have given indications in preliminary negotiations that the player is keen to commit to an extended deal that includes a substantial pay rise.

Arsenal’s position has not changed despite the midfielder being hit hard by the latest serious setback to his career.

Wilshere has three years to run on his existing £90,000-a-week deal but the Londoners do not want to risk a situation where he could be antagonised into pushing for a transfer.

The England midfielder was a target of Manchester United and their neighbours Manchester City in the summer but Arsenal have no intention of cashing in on their academy graduate and will reject any bids for him.

The Wilshere injury is another blow for Arsenal after it emerged that Danny Welbeck is expected to be out for six months after undergoing knee surgery.
