Chelsea roll on under Thomas Tuchel, while Southampton’s alarming nosedive continues, so only one out come is surely on the cards. Timo Werner finally finding the net on Monday is ideal timing too as the German international will not be up against Kyle Walker-Peters, who has reinjured a hamstring. The only optimism to be found for Southampton is some complacency on Chelsea’s part. They face Atlético Madrid on Tuesday so might just be more concerned with getting through without picking up injuries so that they enter Diego Simeone’s bullring unscathed. Graham Searles
