Match of the Day commentator Guy Mowbray: "I think there are many layers as to why Yaya Toure has not been performing at his best for Manchester City. He had a family tragedy and there was the summer with Ivory Coast at the World Cup. The stick is fair because he's not performed as well as he can. When he is on form, for any of the top three or four teams he's the difference between winning title and not. Regarding the City v Chelsea match, I fancy the London side because of the way they have started."
Football writer Amy Lawrence: "City manager Manuel Pellegrini is a measured man, but he came out and said Toure is struggling after the death of his brother. You expect our footballers to always be at the top, but sometimes life's not like that."
Former Liverpool midfielder Danny Murphy: "On today's game, I think with Chelsea striker Diego Costa, something is going to happen with him soon. Every Chelsea match I watch he's on edge all the time. It won't be long before he flares up. The contest between him and City defender Vincent Kompany will be fascinating. I fancy City. Chelsea had the best defensive record, but by playing Cesc Fabregas and Costa you lose the legs. Today will be down to tactics when you have two teams with so much quality."
