Ralf Rangnick admitted Manchester United are not clinical enough after they were held to a demoralising draw by 19th-placed Watford at Old Trafford.
United had 22 attempts on goal but three were on target as they dropped more points in their effort to qualify for the Champions League next season.
Even though United have still lost once under Rangnick, they have drawn four of their last eight Premier League games and only scored at least two goals in four of Rangnick's 17 matches in charge.
