Manchester City manager Roberto Mancini has claimed that the fitness of Yaya Toure will be key ahead of Monday's crucial match with Manchester United.
Toure recently returned from injury and Mancini admits that the former Barcelona midfielder was not at his best during the 2-0 victory over Wolverhampton Wanderers last weekend.
Mancini said: "If Yaya Toure is on form, he is a top player
"But we need him to be 100% and on Sunday he was so-so."
The Italian manager is expected to have a full strength side to choose from for the top-of-the-table clash.
