Level at the top of the Premier League, Chelsea and Manchester City know neither can afford to slip up this weekend. Joint Premier League leaders Chelsea and Manchester City go into the weekend's round of fixtures with a dual purpose of maintaining form and avoiding mistakes. Chelsea host managerless Newcastle United at Stamford Bridge while City are away to out of form Everton. The leaders have 45 points each and an identical goal difference of 44-19. Chelsea are likely to start with Diego Costa after he was a substitute in the FA Cup win over Watford last time out.
