It's funny you say this because this squad Ole has built is primarily made up of players that Jose just simply didn't rate - Pogba, Martial he wanted sold. Rashford and McTominay were squad players in his ideal team. Fred and Shaw were borderline joke figures among the fanbase when Ole took over. And Jose is on record as saying that Greenwood would have had no role under him the season he left.
By contrast, all the players Jose rated and used have either been sidelined or sold. Lukaku, Matic, Sanchez, Herrera, Valencia, Young, Rojo, Smalling, Fellaini, Jones, and most recently DDG.
So I personally think it's an even better achievement from Ole to get us to where we are right now with only 3 or 4 first team signings and the vast majority of the players being the ones that were already here, and it points to his ability as a manager being pretty damn good when you consider that all of those players I mentioned were widely being seen as being part of the worst Utd side since the PL.began at the start of last season.
