Frank Lampard is running out of time as Chelsea manager, according to Roy Keane.
Lampard's side turned in a woeful display on Sunday, falling 3-1 at home to Manchester City in a match that was out of reach by half-time.
The defeat continued a concerning run of form for the Blues, who have won just one of their last seven Premier League matches and sit eighth in the table.
