Sure he's not got explosive pace but he's no slouch either. Admittedly I've only seen clips of him but he seems to be able to pass and shoot with power using either foot, has exceptional close control and, crucially for a player in his position, is always looking to move the ball forward. He's a Spain under 21 international and they don't pick many duffers.
I can't speak for why we are not back in for Sancho, but I imagine that the deal doesn't represent value for money.
Torres for a quarter of the Sancho fee is smart, fits with the club ethos from playing style to financial structure, and is one part of a bigger plan.
I have no doubt if Sancho goes to United it will be hailed as a great move and so on, but the reality is that adding one player doesn't mean they improve on third. They were lucky to finish that high and, for my money, have other areas of the team they desperately need to address. He'll score a few for them, earn them a few penalties, but really will it add anything they don't already have? Yes it is always nice to have English players featuring prominently, but there is a balance to be had. Is he really a €100m player?
United's philosophy of going big has created a huge risk for them. A couple of injuries, bad form or a more 'normal' figure of penalties awarded next season and they may find themselves approaching a billion in debt and Europa League football again if they are lucky. Even with Sancho.
The right move, for both clubs.
