Willian was picked over Juan Mata for Chelsea’s final group stage game against Steaua. And although he showed some nice flashes and neat touches, and looks a lot leaner and fitter than when he first arrived, Willian made no real impact on Chelsea’s play, as they struggled to create much, though the lack of familiarity between himself and Demba Ba was undoubtedly a factor.
