Battle of the 3-4-3 formations I suppose? Seems Chelsea has been lining up:
Pulisic - Giroud - Willian
Alonso - Kovacic - Jorginho - James
I think Ceballos and Xhaka will do well against Kovacic/Jorginho, they're not the type of midfield (fast/runners) that expose our lack of pace in CM.
My main concern is Luiz/Holding stepping too early to Chelsea's intricate passing around the box, and Pulisic vs Bellerin. Could also see Alonso continuing to bully Bellerin in the air if we're not careful (and protected, that fucker).
