Manchester United midfielder Morgan Schneiderlin feels that the Red Devils need to cut down on their defensive errors.
After the 3-2 win against Southampton on Sunday, he said of Louis van Gaal's side: "The manager reminded us yesterday night and this week that we need to be careful if we are in front and too much in control that we have to stay in shape and not be too open, and not let crosses in the box.
The 25-year-old also mentioned that United have already conceded cheap goals to Swansea City and Southampton this season.
He added: "It has happened to us two times this season against Swansea and Southampton. We almost got punished so we need to learn very quickly again."
