Black Adder
Rarer than an eclipse.
More than work rate it's his proactiveness that's been beneficial. Also, he's really benefitting from A) playing as a 10 and B) Having pace in front and decent options on either side. The pass he played to Rashford for the third goal isn't possible when Rooney is up top.
It's not his first match as 10, he's played it before, just wasn't this good!
Agree that he needs runners around to make a good attacking pass, but not just from striker(s), but wingers too, having more than 1 option is crucial in being unpredictable, when you have 1 option up-front and safe pass then you really can't do much.
But him not shying away from duels and tackling, not hiding in the play that's what made the difference from previous matches.
I've said it once about him, he has all the tools in the box to be really effective player, it's about time he starts using them!
