Whether or not we can make it work, I think Ole would be tempted to experiment with a DM, Bruno and Pogba more advanced than the double pivot after seeing him shine there and Pogba himself stating he loves playing at the attacking left
If this is the planned route forward then I think it only works if we sign another CM along with Rice. We'd still need a CM whose strength is in controlling the tempo and is an effective player at progressing the ball though midfield. If we could find the right player for that role then Rice would start to look like a very good signing. However then I'd wonder about Sancho for the RW. Would it really be effective to have 2 playmaking wide men instead of having more typical winger with pace who can beat a full back.
