Lukaku has been at Manchester United for two seasons, since sealing a move from Everton under Jose Mourinho in the summer of 2017.
But he has struggled to make a name for himself at Old Trafford, despite scoring 42 goals in 96 appearances.
Inter has emerged as a strong possibility for his next destination and Lukaku appears keen on a move.
“Well, Conte has gone to Inter, for me he is the best coach in the world.
“With regards to my future, I have already made a decision that I still cannot reveal publicly, out of respect to Manchester United with whom I still have a contract,” Lukaku told Sportmediaset.
Lukaku went on to reveal his admiration for the Italian top flight, pointing to a string of high-profile recent arrivals to suggest it was a league on the rise.
“I am a big Serie A fan, those close to me know that I have always wanted to play in the English league and in the Italian: I love Italy,” he added.
“And then Cristiano Ronaldo arrived, [Maurizio] Sarri is going to Juventus, [Carlo] Ancelotti will be at Napoli: Serie A will be exciting.
