I hope Carvajal isn't fit, as his crossing can be a problem. He's quite solid defensively and a danger going forward. Danilo is a disaster, and Nacho is ok defensively but doesn't pose much of a threat in the final third. I'd rather Bale start over Isco; Isco has been on fire lately. I'd be wary of Asensio coming off the bench, and the curse of the ex (Morata). Needless to say, Ronaldo is still the danger man.
I'd start the same formation as against Monaco, and leave Cuadrado on the bench, just in case. Neto, Benatia, Licht, Asamoah, Marchisio, Cuadrado, and Kean on the bench. It's a shame both Rugani and Pjaca are injured. There's no point in putting bums like Rincon, Lemina, or Sturaro on the bench. They aren't impact subs, and are unlikely to change the momentum of the game, if that's what is needed.
