If you replace Smalling, Young, perhaps Lukaku in place of Lingard, Jones/Rojo, Darmain and get Carrick type player in place, we probably would average more possession
Ole has been alway favoring possession based but he didn't implement his style fully in place on us yet, he has us to play our strength since this is not his team. Cardiff, Bournemouth, Huddersfield, etc we were experiencing a new style of play under Ole but it is more risk, as we went through every game, we went less dominant and more counter-attacking.
This is one of the reasons I hope to see a massive change next season if he stays for next season and able to implement his style in place fully, we need to improve our balls retention/control and carrying the ball, awareness of surrounding, an understanding between people's movement and off-ball movement, pressing as a unit. Get rid of Matic for DLP like Jorginho, De Jong, Busquets, Pjanic and replace Young with a silimar technical fullback like Shaw, replace Smalling with top CB who is very comfortable on balls under pressure.
To be honest, I don't like watching any team dominating balls against us and us defending for life, it gives me a headache and frustrating.
