Arsenal boss Arsene Wenger is adamant Watford didn't deserve their penalty for Saturday's 2-1 win.

With the Hornets down 1-0, Hector Bellerin was controversially deemed to have felled Richarlison by referee Neil Swarbrick. The penalty turned the game, which Watford went onto win 2-1.

Wenger said: "We were unlucky. That penalty was a bit ridiculous.

"I think it's a scandalous decision.

"We got ourselves into many situations when we could have scored, but we did not take the chances.

"In the first half we played extremely well."
