Arsenal manager, Mikel Arteta, has given reasons for his side's 2-1 loss to Brighton on Saturday.
The Gunners who lost 3-0 at Manchester City on Wednesday, took the lead through Nicolas Pepe in the second half.
However, Lewis Dunk forced the ball in for 1-1, before Neal Maupay grabbed the winner late on.
Arteta, speaking to BT Sports after the game, lamented his side's profligacy in front of goal.
He said: "It's unacceptable the way we lost today.
"We missed so many chances, we gave them the first goal, and we didn't compete in the second goal."
