Mourinho says he enjoyed the best time in his career at Inter.
Mou said: "I left because if you win with Real Madrid then you make history. However, my heart remains Nerazzurro.
“Nobody has given me the same sort of happiness that Inter have. I cried on more than one occasion when I left. My heart is in Milan, I have an ever-present nostalgia for Inter.
“Inter are a family and I will always belong to that family. I celebrate when Inter win and I suffer when they lose.”
