José Mourinho said he will leave Inter after guiding the club to a historic treble, culminating in their first European Cup victory in 45 years.
"My work here is done. I have made history with this club," the former Chelsea manager told Rai Sport after a 2-0 victory over Bayern Munich. "I will find motivations in another big club. Playing against Barcelona in Spain? That would be a big challenge."
Tens of thousands of sleepless Inter fans welcomed back the Nerazzurri on Sunday, but their talismanic coach Mourinho was not among his players. Mourinho is understood to have stayed in Madrid with family and friends.
"I have been very happy at Inter, but not in the world of Italian football because I don't like all the comments from presidents, coaches and papers," he said. "But, I will always like Inter. I want to thank Italian football because I have become a better coach for it. Now it's time for me to take a day or two to think about a new challenge in another country.
"I have given everything for this team and I feel free to make a decision on my future. I want to become the first coach to win the Champions League with three different clubs. It's more probable that I'll go than stay."
"Everybody knows that English football is my passion and I'll go back to England once," he told Sky Sports. "But I think every player, every coach if you don't play for Real Madrid or if you don't coach Real Madrid you have always a little space in your career. So if I decide to come to Real Madrid I'll be a very proud man."
"This makes me feel really sad," Mourinho said. "I've become part of Inter's history and I don't want to talk about anything else. If I talk about it I'll cry and I don't want to do that."
Still, Mourinho again addressed his likely move to the Spanish capital.
"I want another challenge in my career and now it's the moment to decide," he said. "The important thing for Inter is that (club president Massimo) Moratti and (captain Javier) Zanetti stay."
Mourinho was asked on German television channel SAT1. "Was this your last game for Inter?
"Yes," he replied.
"Where are you going, are you going to Real?"
"Yes," he said.
Over 100,000 fans thronged the streets of Milan to party, after gathering in the seething Cathedral square, waving giant flags and setting off flares and fireworks.
Just as dawn broke the plane carrying the team touched down at Milan's airport, with an Inter flag flying from the cockpit window.
Captain Javier Zanetti held up the cup for around 40,000 restless supporters, who gave a huge roar when he led the team into the stadium.
Earlier, in Madrid, Diego Milito finally hit the global headlines with two goals to clinch the European Cup having previously gone about his business almost unnoticed in the wider world.
Nicknamed "the Prince" in Italy, the Argentinian will now be acclaimed as the King after showing his customary calmness with strikes either side of the break to down Bayern 2-0 in Madrid's Bernabéu stadium.
"It's a joy I've never experienced," said Milito. "Incredible. I am so happy for Inter because we wanted this so badly. We are so happy and it's a unique sensation. I have always battled, trying to give my utmost, to learn, even if I am 30. I'm so happy, we deserved it," he added before being coy about whether he will stay at Inter next season. "Let's see," he said.
"Mourinho deserves this the most. He is great coach and he deserves all of the credit for this success," he said. "This is the team that he has made. He made many changes to the team that finished last year and we have come so far."
