Newcastle United legend Alan Shearer feels Yaya Toure is the title difference at Manchester City.
He explained in The Sun: "Everyone is looking for what will make the difference in the title run-in.
"Well I think I saw it on Saturday in Yaya Toure. Man City had wobbled while he was away at the African Nations Cup.
"Now he is back and a solidity has returned. Nobody is more key to Roberto Mancini's cause."
