Arsenal manager Arsene Wenger was left unhappy by the amount of stoppage time played in his side's 1-1 draw at Sunderland.
Darren Bent netted a last-gasp equaliser for the Black Cats in the fifth minute of stoppage time, with only four minutes having been put up on the fourth official's board.
Wenger said afterwards:"If you have a watch, you can control. It's as simple as that.
"It was outside the four minutes. I know the referee can give more than four, it's a minimum of four minutes.
"But in the four minutes nothing happened to justify the extension of the time. But I cannot do anything about that."
Meanwhile, Wenger was pleased with his side's overall display at the Stadium of Light, adding:"I believe the performance was good. We had problems to start in the first half.
"In the second half we played very well. We were, even with ten men, in control of the game and unfortunately in the 95th minute they equalised.
"I was very pleased. We could battle, we could play, we had all the ingredients of a good team. We had a slow start, but in the second half we did well."
