Saka beat his marker well a couple of times, but after doing the hard part, he often kept his head down and didn't look where he should pass. Or just otherwise failed in the final ball. Although Aebischer and other Swiss subtle fouled him, nudging him just a bit to put him off balance before passing without ref noticing.
Otherwise there was no threat from left flank nor from the middle, which was too crowded for Fode, Bellingham or Kane to do much.
England just up the tempo and try to attack more when the ball is turned over and there's at least a bit of chaos on the pitch.
If they choose to control the ball instead and try to build up slowly, Swiss are just too organized for England to break them down. Mainoo at least has tried some quick forward runs from deeper.
