Not sure if anyone has picked up on this but when BBD was playing on the wing, he knew he didnt have the beating of his man and always went backwards, this enabled the opposition always to step up as the CBs didnt have to worry about being out of position to cover if he went past them. Now Donovan playing there, the full back knows hes going to get past him or have a go, which then pushes the CBs back in a positional cover rather than an aggressive push on the forward line. It moves blades further up the pitch and the opposition further back. Thus more room for peck & KP in the middle to dictate the play and take control of the game.
It’s amazing what a slight tactical change can do to move a team much further into their own third.
