Yes, for me. It's not even a debate IMO, as their points and results show. They've rotated better not just out of necessity but also because they can afford to trust the bench. Do Chelsea get anywhere near their points haul without Costa, Terry, Hazard and Matic for parts of the season, like they've had to? Schurrle is on some weird decline, Salah, Luis and Remy are ghosts and bizarrely not in the trust circle somehow. Rami has been unlucky and Mourinho's untouchables policy hasn't helped but I think they do have in-form and better performing alternatives.
