If your front 4 are giving the ball away every 10 seconds, how on earth could we have the game under control? Every time Bruno, Sancho, Ronaldo and Rashford lose the ball is another potential counter attack for Norwich, another transition for Norwich that we have to defend against, another chance for them to play the long ball over the top of our defence to chase, another chance to get the ball forward where they can win free kicks around our box, and win corners that put us under pressure.
Fred and Mctominay are not superhuman that they can win the ball back within seconds every time our front 4 lose the ball. They lose the ball so often it's literally impossible for us not to be under pressure at points in the game.
