Arsenal's board is prepared to change manager during the season.

The Sun says manager Unai Emery has until the new year to turn things around at Arsenal.

Club executives believe the next four Premier League games against Southampton, Norwich, Brighton and West Ham are a golden opportunity to lift the mood at the Emirates.

But it is the five games from mid-December to January 1 — which include meetings with Manchester City, Chelsea and Manchester United — that will decide Emery's fate.

And if they find themselves with no chance of achieving Champions League qualification through their league position, the club will reluctantly look to replace the struggling Spaniard.
