Manchester United sunk to a third successive loss at Goodison Park.
Manchester United boss Louis van Gaal looked miserable as his side were defeated 3-0 at Everton.
The Red Devils were off the pace from the first minute against an inspired home side, who put in one of their best performances of the season.
Van Gaal is the third Manchester United boss to lose at Goodison Park in as many seasons, following David Moyes and Sir Alex Ferguson.
United were not helped by a glaring miss from ex-Evertonian Marouane Fellaini early in the first half as he blazed over whe through one on one, when the side were just 1-0 down.
Van Gaal told the club's official website he was disappointed with his side's efforts, stating: "Everton had more aggression and motivation than us and that is the first time I have seen that this year, so I was very disappointed by half-time.
"We could not restore [the score] because Everton defended very well and played on the counter attack. Then it is always difficult."
United have now lost two games in a row, beaten at Stamford Bridge by Chelsea last week, and have slipped back below rivals Manchester City who they overtook a fortnight ago.
Van Gaal added that his side have now given Liverpool hope in the race to finish in the top four, but they could take solace in the fact Brendan Rodgers' side could only draw against West Brom a day earlier.
