As far as United's calendar go, I feel Lukaku is up to the challenge against any team. But I might switch Valencia for a defender from City which has a easier run, and not sure what Mikhtaryan can bring me (Martial might be a better shot). As for City, Silva and Jesus will stay. Without Morata, i'm not sure what Chelsea can do, even with a couple of easy games ahead - so i stay away from them. So, I am now thinking more little teams like Leicester and Newcastle, they have "easy" games ahead.
