Five questions to pass the time as we await kickoff from Moscow.
1) 3-5-2? 4-3-3? 4-6-0?
2) Does Conor Coady get his first appearance of the season?
4) Better option up front--Samed Yesil or Adam Morgan?
5) How does Group A look top to bottom after the fourth round?
Bonus: How badly would a Rafa Benitez-led team lose this fixture? What if he had a squad full of Gerard Houlier's players? But also Roy Hodgson's? Kenny Dalglish is there too, maybe.
