Roberto Mancini on Yaya Toure
"We are building a team. There are players that change the look of a team, and Yaya is one of them.
"Next year we could try. We need to bring three champions, and we will see that we will be ready to fight for the Scudetto."
Toure is under contract with City until June 2017 and has scored seven goals in 18 Premier League appearances this season.
Mancini, who led City from 2009 until 2013 and oversaw their maiden Premier League title success in 2011/12, returned to Inter last November for a second spell at the San Siro.
