As much as I think he'd improve you and certainly wouldn't complain if he came to City, Sanchez should go to United. We've found a balance with Sterling, De Bruyne, Silva, Sané and Aguero/Jesus that shouldn't be unnecessarily disturbed with so much of the season still to go. If we're going to go for another attacking player - which we do need, in fairness - we should be looking at someone who can rotate with Aguero and Sané, not take their place in the side, especially not someone who'll be 30 in under a year. A young, direct winger who can play on both sides is the sort of player we need for the long-term. I'm sure Sanchez would give us a great boost for the rest of this season but I'm not sure how much more of a boost we need. We're fifteen points clear in the league (it'll be 12 points by tomorrow night, but all the same), into the knockout stages of the Champions' League, and halfway to a cup final, and we've achieved that without Sanchez. Beyond the summer, what happens? Does Aguero leave because Sanchez is Guardiola's first choice, only for Sanchez to decline in a year or two? Does Sané have his development hindered by Sanchez taking his place? Like I said, he's a fantastic player and I'm not exactly happy he's going to United, but I'm not sure where a player like him fits at City without affecting the balance we've discovered.
