I'd be inclined to have Fab at CB, not in midfield. I don't like the idea of Phillips and Kabak having to deal with the fast Chelsea front line. Fab isn't quick but he showed in the first game against these how well he can play fast strikers, so I'd prefer him there than midfield.
Theres no point having him in midfield pressing if Chelsea can just play long balls over his head that Phillips and Kabak will struggle with against Werner, Pulisic etc.
Midfield from Gini, Thiago, Curtis and Naby (if fit).
Would take a draw here, I can see a few others would too. A win, with results last night, would be huge, but a draw is an okay result.
