Given the minutes AOC has seen I think there's no chance he starts against mostly rested Crystal Palace. Keita has more of a chance.
But since each of Fabinho and Gini have had a game off, and since Gini owned Zaha there last season, they are guaranteed starters. Think a fresh-legged and virus-free Henderson is probably bound to start, even if people would rather not that midfield three if Salah is unavailable.
Think we might see a Gini and Fabinho two, then Henderson much freeer on the right, Fimino behind our striker (Salah if fit). Then Origi on the left with Mane up front if Salah doesn't make it. Guess there's an off chance Keita starts and he and Gini take turns further forwards on the left.
Not certain but I think that Roberston is a lot better than is being made out to appease the Scots. Milner fine there, if not.
