I think he's very talented but not what we need right now, this forward line needs an experienced player added to give us what Sanchez was supposed to give us, not another kid. Plus if Rashford is going to play as a #9 the 4-3-3 is not going to work, look at how vital Firmino's hold-up play is for that Liverpool front 3, or how Sterling, Sancho and CHO all played off Kane's work as the central pivot in the recent England games. That's not Rashford, he gets knocked off the ball too easily and is best when running in behind and relying on his movement, not with the ball played into his feet where he acts as an attacking fulcrum for the wide forwards. You have to look at it like a jigsaw, people are obssessed with the right side but you need the #9 that can facilitate the right side as well. The 4--4-2 diamond is when we look at our best and Sancho doesn't really have a key spot in that formation right now.
