Rio Ferdinand has said that it is time for Arsenal manager Arsene Wenger to know when enough is enough and to quit the club.
The former Manchester United and England centre-back, who was once the most expensive defender in the world, drew parallels with the end of his own career, which petered out in disappointing fashion at QPR.
Wenger, though, appears determined to keep a grip of power at the Emirates Stadium, despite admitting that the Gunners have gone backwards this season.
His side are closer to bottom side West Brom than they are to league leaders Manchester City and are unlikely to qualify for the Champions League next season via a top-four finish.
