Graham Potter praised the impact of Wesley Fofana after his second-half header earned Chelsea a much-needed 1-0 win over Leeds to bring respite for the manager. The defender was making his first start since the knee injury he sustained against AC Milan in the Champions League in October, and was brought into the side with Thiago Silva and Reece James ruled out. The Brazilian Silva, one of Potter’s most influential leaders, is expected to be out for around six weeks after being forced off during last Sunday’s defeat to Tottenham.
