He plays in a double pivot more due to the managers he plays for. Southgate and Moyes; whilst the way he plays is actually much more like an anchor man that shield 2 CB's behind him and 2 CM's in front - ie the triangles of the 433.
This is why we hope that he can come and switch Ole (who has also been a double pivot guy at United/not all the time at Molde) to a 433.
The one thing I will say though is that even in a double pivot I notice that Soucek gets a crap load of freedom to get up and down to the pitch and really have a go at attacking. It's still a double pivot, but one of the pivot is at the other end of the pitch quite some times. Whilst I hope it doesn't happen- if the 4231 does stick and Rice gets stuck in a double pivot with Pogba (the younger quicker version of Matic Pogba partnership) - then I can see Pogba getting forward and really having a go at attacking even in a double pivot because Rice does his duties of shielding the defence first and foremost before anything else and will be there covering alot of players that have left for an attack.
This is what I’ve been saying for at least a year or so, Rice is a pure out and out defensive midfielder who’s sole job and best role is simply shielding the defence and allowing other players to go forward.
Yes he plays in a two man midfield with Soucek but Soucek always has licence to go forward and is always safe in doing so because of Rice behind him so Pogba could do the same but even better because Pogba is a far better player than Soucek, having Rice in front of Varane and Maguire would create a 4-3-3 that could basically be a back 5 and front 5 with a higher line but it’s if Ole has the balls to play a 4-3-3 even though he’d have the players.
I think a starting 11 of De Gea, AWB, Varane, Maguire, Shaw, Fernandes, Rice, Pogba, Greenwood, Ronaldo and Rashford with Henderson, Lindelof, Tuanzebe, Telles, McTominay, Fred, VDB, Sancho, Diallo and Martial in reserve is perfectly balanced as a squad but again it’d be whether Ole could get it right tactically which I unfortunately don’t think he can.
