"This is what happens when you only play for 45 minutes," Evra told MUTV. "The game is 90 minutes long and we deserved to lose because we only played for 45.
"To concede three goals at Old Trafford is not good enough when you want to win the game. The problem is about our heads – it looked like we stayed in the hotel.
"The first 45 minutes had no speed, no focus, we didn't win a lot of challenges and we conceded some silly goals. Maybe I am hard with myself and the team but we only showed the United face in the second half."
United are now third in the league table with 12 points from six matches, four points behind leaders Chelsea.
