Arsenal boss Arsene Wenger admits he is very disappointed with the way his side conceded goals against rivals Tottenham in the north London derby at White Hart Lane.
World Cup winner Mesut Ozil gave Wenger's side the lead in the 11th minute. Harry Kane drew level in the 56th minute and scored the winner with four minutes to go.
The two goals the man-of-the-match award winner scored, were the first Arsenal had conceded in the Premier League since New Year’s Day and the Frenchman is convinced his players should have done more to keep Spurs quiet.
"It's very disappointing because we started very well and then thought too much about defending, and not enough about playing," the Arsenal manager told Arsenal Player.
“I felt we made too many technical mistakes in the middle of the park, and lost balls that are very unusual for us. On top of that, we gave two cheap goals away and that explains the defeat.
“The corners on the deflection, we could have [had] the ball and then on the second post we leave them completely free. On the second goal, I felt that we left them completely free to cross the ball and then had nobody in position.
“Before that, we could have won the ball in the middle of the park and if we had won it, we could have gone through. But we didn’t really go for the ball and after that, Kane had a completely free header in the box.
“With five minutes to go, that’s difficult to understand with the experience we have at the back. I’m disappointed by the quality of our football and it was just not good enough.”
