Since replacing Wesley Fofana against AC Milan in early October, Trevoh Chalobah has barely left the pitch for Chelsea. The injury to his French teammate combined with the need to rest Thiago Silva has seen the young Cobham product become the consistent presence in Chelsea's backline, with his first substitution coming against Manchester City.
That perhaps makes him better placed than most to dissect the Blues' difficult period that has seen three defeats in their last four matches. The 23-year-old conceded that his team were still learning from Potter but are making progress.
Chalobah believes that even in defeat, Chelsea showed progress against Manchester City. However, he did not mince his words when describing the importance of Newcastle and the club's final Premier League fixture before the break.
