Of course it easier to perform well when you have other good players around you, that is true for every single player. It's pretty obvious that it's easier to perform well when you play with midfield partners like Pirlo, Vidal, Marchisio and Kante compared to when you play with players like Padoin, Struaro, Fred and McTominay.
Imo in midfield the key is to have a good mix of characteristics. Pogba will never be able to do the things Kante does just like Kante will never be able to do the things Pogba does. In a well constructed midfield Pogba doesn't need to be Kante, he brings different qualities into the team.
