Liverpool was also a L. Just getting a draw there and winning against Palace and Nottingham difference now would be 2 instead of 9. I fully expect Liverpool to start dropping points now so yeah it's very important to win here.
No need for rotation. Play your best team in all 3 games just like we would and everyone else does in Champions League midweek. This is first time this season we have this situation so it's really not necessary to rotate. Only attackers maybe because we have quality on the bench and even in starting 11 it is a dilemma who to play. I imagine Enzo and Lavia may change depending on opposition but defence we cannot touch because difference in quality is significant.
