I think I read somewhere that we haven't won a single game in PL coming off an International break under Mourinho, the only points we've dropped this season at Stoke were after an Int'l break.
This is the worst possible place to go to, you know they'll be up for it. Expect their dodgy defence to play out of their skins and contest every second ball as if their lives depended on it. Big test of our title credentials.
Also, why are people advocating dropping Mkhitaryan in favor of Lingard? Rashford is absolutely nailed to play as a LW to help the full back cope with the pace of Salah. Having Lingard would completely take away any threat on counter. Mkhi is frustrating as he loses a lot of possession but with Pogba out he's the only guy who can set us up for a quick break.
Formation is a big question, Fellaini's form is too good for him to be dropped but we also need Herrera's tenacity in the middle. I think he'll go with a normal back four with Darmian as a LB and Matic, Herrera, Fellaini in the middle. Rashford, Lukaku, Mkhitaryan up top.
