The 31-year-old defender has played a key role in the Citizens first-team this year, stepping into the heart of the back-line to cover for injured captain Vincent Kompany.
However, with Toure's contract set to expire at the end of the campaign, speculation has suggested the Manchester City stopper could leave the Etihad Stadium this summer.
Asked in today's press conference whether he planned to offer the African enforcer an extension to stay with the Premier League champions, Mancini remained tight-lipped over his future.
"I am also leaving in the summer - on holiday," responded the Italian, to questions from the press. "We don't know at this moment. What is important is that he continues to play the way he did on Monday night and against Chelsea.
"Kolo is a really professional player and deserves to have the satisfaction of those performances. He has done really well and we will see. I am happy for him because he is a good guy."
Toure is currently in his fourth year with Manchester City, after signing from Arsenal in a £16million deal in 2009, and was joined at the Etihad by his brother, Yaya, a year later, when he joined from Barcelona for an even bigger fee, reportedly amounting to £24million.
