Defense is not about a defender but a defensive system
so no matter how good a defender is, he can't stop anything on his own
a midfielder needs to get the ball but it is not the only duty he has, he could get it sure good but he won't do that every time otherwise you don't need defenders
he still can do good without getting the ball, by making it easier for the defender
so if he got beaten, the player with the ball wouldn't be 100% balanced and controlling the ball
it could get a bit further than he wants, he could struggle to stay on his foot
that makes it easier for the defender to get the ball and doesn't mean the midfielder made a mistake
so your attacking players they need to have fewer defenders to beat, or else they beat one or two then the ball is easily taken from them
but how is Leao getting that? nobody is there to distract some of the defenders to open space for Leao for 1 on 1
because Giroud and Diaz are joining the midfield trying to get the ball back, it is then passed to Leao who is alone against 3-4 defenders focusing on him
so fails and keeps on failing until he gives 150% and get past 2-3 players then he can't focus on shooting after all that wasted energy
so fans don't get to notice what he is doing because it doesn't end with a goal or a big chance.
