He didn’t need to slide though. I still have no idea why he did. Putting the ball into touch was the bare minimum there. An international player should really just be taking a touch and passing it back to the keeper to retain possession.
Dunk has this really strange thing of being terrified of big strikers. He’s always been rubbish against Mitrovic, for example. That goal was like watching a year 7 shit himself being chased by a year 11 to get his ball back.
In all fairness they probably didn’t expect dunk to end up on his arse when he had 10 yards on Lukaku and could have just simply kicked the ball into row Z
