I want Sancho quite bad. But when Mason is playing so good on the right, I just hope Mason still gets enough chances as I think he is just as talented.
Would like them both though, and the headache where they both play after.
I agree but you need to realise having Sancho also offers versatility.
You could play a 4231 in some games with Rashford, Martial, Sancho, Greenwood, Pogba and Bruno in some games.
Other games you could do a 442 with Sancho at LM and Greenwood at RM, and Rashford+Martial up top, again Bruno and Pogba in midfield.
Pogba is capable of playing defensively, and Bruno we know applies a lot of pressure so even those 2 playing slightly deeper roles but going forward when needed is an option against lower teams.
In games where 433 is an option again it can be an option, Pogba playing deep making challenges.
Against stiffer opposition Sancho or Mason can rotate, but a big squad is needed to challenge on all fronts, yes Matic and McTominay will obviously be playing in bigger games, but the fact is the team can be overloaded with attackers sometimes when required.
Mason would still play in FA Cups, against (perhaps not the top 4) but still a lot of games with less defensive midfielders playing but Pogba as a CDM / Deep-lying playmaker.
Mason would also be there in qualifying games in the CL etc.
There will plenty of options for Mason, and for all Mason, Sancho, Martial and Rashford to play at the same time (which I see being a real option at times).
