Manchester United are the 'unluckiest team' in the Premier League, says Jose Mourinho.
Juan Mata handed the Red Devils the lead with a sublime strike in the 68th minute, but Olivier Giroud headed home with one minute of normal time left to go, making it the third league draw on the bounce for Mourinho's side at Old Trafford.
"We are the unluckiest team in the Premier League," the Portuguese told Sky Sports.
"In the last three matches at home, against Stoke we have to win 5 or 6-0 and we draw, against Burnley we have to win 5 or 6-0 and we draw and today we have to win 2 or 3-0 and we draw too, so I think we are the unluckiest team.
"But the team is playing well, the team is working really well."
Mourinho continued: "We were the best team by far. I don't want to say they didn't want to win, but they had no chances to win.
"They couldn't be Arsenal the way they normally play football. We were phenomenal defensively - the way we pressed, we were very strong without the ball, controlled their counter-attacks, their best players.
"When we had the ball we were very comfortable. We played quality football, we scored a fantastic goal. We had chances to kill the game. The Marcos Rojo and [Paul] Pogba situations for the 2-0 were open goals and then the only time we had a situation that we couldn't resolve they scored the goal.
"So they were the lucky ones and we were unlucky, but that's football."
