Asked if Toure would be on his way in the summer, the Italian joked: "I am also leaving in the summer - on holiday."
"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."
