Manchester City midfielder Yaya Toure says Chelsea are favourites for this weekend's showdown.
Toure believes Antonio Conte's side have an advantage over City due to their lack of European football in midweek.
"It's going to be a tough game on Saturday, that's for sure," Toure said. "They definitely have an advantage. It's difficult to play midweek and then the weekend after.
"Sometimes with the European schedule we play on a Wednesday, like this week, and then a Saturday. It's sometimes tough to be focused and in these kind of games, you have to prepare well to compete."
