Sancho will be joining a top 4 team and I can't see it being City with the way he left the club.
We finished 32pts behind City last season and only signed two clear upgrades in Maguire and AWB. So it's realistic to see us finishing in the top 4. I'm pretty sure the club will make a concerted effort to sign Sancho and have probably already done some of the leg work if the BBC is to be believed. If not Sancho then there's also Federico Chiesa we could go for.
Mason is a striker and will eventually be the #9 playing through the middle. He isn't a winger and shouldn't be seen as one long term IMO.
Of course he'll be joining a top 4 team. But my point is, does he want to join a club that is only aspiring to be top 4? Why not league champions or chellengers?
I don't follow your point with the bolded part. Finishing so far behind City means we will probably make top 4, despite only 2 signings to the first team? I agree that we'll try to sign him, but i don't see what has changed now that will convince him we've turned a corner. I don't necessarily think he aspires to play for a team that aims to qualify for Europe, which is what some seem to have convinced themselves. I think he wants to sign for the Manchester United we used to know that competed on all fronts.
I agree re Greenwood being a Striker per se. However I can't see him jumping ahead of Rashford and Martial for a few years yet, especially under Ole who I think has a lot of time for Rashford. His best bet is to make that RW type position his own and integrate into the team. I like the look of him there and having watched him there, I'm less sure he'll 100% be a striker. He could make that spot his own or learn his trade there before being moved up front in the future, is what I'm trying to say. Another thing worth mentioning though is that our RW literally never has to hug the touchline, they spend most of their time drifting around the striker. We look like implementing a flyid front three with no fixed position, so they all need to be flexible. It's good for his development. I'm certainly not ruling him out for this role.
