He's a very smart player, makes very good decisions, has a very good eye for a pass, technically very good so will be excellent at linking up play, has really good movement to pick up pockets of space to play in, very good close control, he's good at moving with the ball, he's elite at creating chances and progressing the ball forward and progressing the ball into the box, he's a decent goal threat from the wings though that is a side benefit with him. Jadon Sancho is the sort of player who our attacks should flow through to get to that final touch, be it through his link up play or his ball carrying to get the ball into the final third or the box. He's a hard worker defensively as well.
Literally he just needs a team that has a defined system. Which is what United needs. He's shown plenty of flashes but it's been impossible for anyone to look remotely decent in this side.
