Where was this Diego Costa?
Costa got yet another goal under Hiddink, his fifth in the last six games and he looked every bit as the fighter that was causing defences all sorts of problems last season. This Costa was not the player putting on and going for Chelsea in the first half of the season but now seems to be back to his best.
He harried the Everton defence in the second half and linked brilliantly with Cesc Fabregas for the first two Chelsea goals. Chelsea fans will be happy with his performances now but they will also be thinking why wasn’t he playing this well earlier?
