I couldn't believe that. He was right that there wasn't much distance between the ball being played and the ball hitting the arm, but he literally swatted the ball away with a swinging arm. An undeniable motion of the arm towards the ball. As deliberate of a handball you will see.
He then said a 'handball' later on was 'much worse', when a Bournemouth player turned his back and leapt to block a cross, and it hit an arm that was left outstretched. He has no idea where the ball is, and just does that instinctive turn and jump to make the block. The 'Deliberate' part of the rule doesn't seem to matter anymore to pundits. Analysis seems to focus completely on distance between the ball being struck, and the hand/arm contact.
I don't think anyone knows what is and isn't handball anymore.
