White Jaidi, from my perspective, there shouldn't be any ambiguity regarding the penalty. Clayton flicked the ball up, it hit your CBs chest and then deflected onto his arm. In response to this, rather than making an attempt to move his arm out of the way, he instead extended his arm in a sort of pushing movement, which then moved the ball from the danger area that Adam Clayton had gotten himself into. It's a clear handball and there's no question with regards to whether or not the penalty stands as the correct decision.
