Giggs was saying how much Nev used to practice making a good connection on saves so when he punched it, he punched it away and completely out the area, and that is a very much an 80's british keeper, Not catching the ball isn't really Pickfords issue.Pretty sure they'll have worked out that punching is better than catching when the risk of spilling the ball is factored in.
Very British thing to get hung up on too. Like the obsession with "not getting beaten at the near post". Better to get positioned in the best place to minimise a goal not the best place to minimise a goal in a specific area of the goal.
