Webb said on Michael Owen's Match Officials Mic'd Up: "The referee on the field recognised that Odegaard had slipped and saw his arm go to ground, we've talked in the past about supporting arms if somebody breaks their fall with the arm it's very natural, and that's a pretty well established concept.
"In this situation, though there's an important difference to a normal player that's fallen, it's not just Odegaard accidentally falling onto the ball. He does slip, the arm does go out, but he actually pulls his arm back in towards his body which is when the ball makes contact with the arm.
"The VAR looked at it and thought it was a case of Odegaard trying to make himself smaller by bringing the arm back towards the body. That's the element that's important here - whether it's instinctive or deliberate he gets a huge advantage by bringing the arm back towards the ball, and the feedback we got back was very clear; the game expects a penalty, in this situation. I would agree, and as such I think this was one that didn't reach the right outcome."
