Arsene Wenger believes Arsenal could have taken something from the game.
"I believe yes, because we gave everything," he said. "The game was very intense, both teams were well-organised, the intensity of the game was very high and on a very bad pitch.
"Overall the technical quality of the game suffered from a very bad pitch and that was why on both sides you've seen unusual technical mistakes."
Wenger added: "I don't think we failed to deliver; we lost a game and that can happen here."
Arsenal have never under Wenger, not gotten at least a point at Old Trafford, and then gone on to win the league. Why can't he just admit that they played poorly.
