Roy Keane fears "heads will roll" at Old Trafford if Manchester United crash
out of the Champions League next week.
Keane believes domestic success alone is no longer enough to satisfy supporters and coaches.
Sir Alex Ferguson's side have a mountain to climb in Europe's elite tournament as they travel to Germany to take on Bayern Munich already 1-0 down from the first leg of their quarter-final encounter.
Failure to turn things around could inspire the United boss to make changes in his final season in charge, according to Keane.
