Former Manchester United captain, Gary Neville, has claimed the current set of players were complacent in their 1-0 defeat to Everton on Monday night.
The Red Devils failed to beat the visitors, who went down to 10 men within the opening 15 minutes, after Idrissa Gana Gueye was shown a red card.
Instead, it was the Toffees who scored the decisive goal in the first half, through Kiernan Dewsbury-Hall.
