Manchester United's defeat to Sheffield United had been "in the post", according to Paul Parker, who says the "complacent" Red Devils' luck ran out in their latest Premier League outing.
United's 13-game unbeaten run came to an end in stunning fashion at Old Trafford on Wednesday night.
Bottom-of-the-table Sheffield United picked up only their second victory of the season to date in Manchester, with goals from Kean Bryan and Oliver Burke cancelling out a Harry Maguire header for the hosts.
