Manchester United boss Ole Gunnar Solskjaer says his players need to wise up.
Against Crystal Palace, Daniel James appeared to have salvaged a point for United with just a minute of regular time remaining, but United could not see the game out and Patrick Van Aanholt earned Palace a first league win at Old Trafford in 30 years as he finished off a swift counter-attack three minutes into time added on.
United enjoyed more than 70 per cent possession against Palace and had 22 shots at goal.
"We have to learn and we have to learn quickly," said Solskjaer.
"From the last two games we should have got six points out of six if you look at the games as a neutral.
"We're two missed penalties away from sitting there smiling, happy with nine points."
