"I hope there will be an opportunity for Mario and Carlos to return to Manchester in the Champions League," Toure told The Mirror. "When we lost them, I felt bad.
"Mario is not just a friend, he is like a brother. I like him a lot and I was very unhappy when he went to Milan. It was difficult for him [in England]. I tried to counsel him and help him.
"Carlos is superb, my favourite striker. I adore him. He is one who works very hard, he is a great professional and friend. With him, Juve will do very well."
Toure captained City as they beat West Ham United 3-1 on Saturday evening.
