Rooney was shit.
Pogba was shit.
Smalling was shit.
Martial was shit.
Everyone else was shit.
If you replace shit with shit, you'll get shit - no gain.
We have good players but we haven't found the right combination, yet. The squad became too tall, but we are not Stoke. If I was Mourinho, I'd try to bring Zlatan and/or Rashford from the bench in the second half, to mix things up, as needed. Rooney will start because he is the heart and the captain of the team. Also, perhaps we need Carrick. Yes, he will be replaced eventually, but right now we do need some continuity and some leadership from our senior players.
