Sir Alex Ferguson has accused his Manchester United players of not being ruthless enough this season.
United slipped five points behind champions Chelsea in the Barclays Premier League at the weekend following a goalless game at Sunderland.
But it is the points dropped in draws at Fulham, Everton and Bolton that have most irked their manager.
Speaking to the club's official magazine, Inside United, Ferguson said: "This present team doesn't kill off sides as well as they should.
"At Goodison, we had three or four chances at 3-1 to really put the game out of sight, but we were wasteful and ultimately paid the price.
"That killer instinct just isn't there at the moment and it's something we need to develop."
