Chelsea boss Thomas Tuchel insists he and Antonio Conte are fine.
Former Inter Milan coach Conte has questioned Tuchel's use of Romelu Lukaku this season.
But Tuchel, attending the Festival dello Football, declared: "I saw him in the hotel before the match, I know he commented on the Champions League match. I didn't hear him personally, but I'm sure he didn't criticise me: if he analysed the match specifically, he's right, because Lukaku didn't played to the best of his ability.
"But in general I can say that we have adapted to his style of play, and that he has adapted to ours. We are still studying how to make Romelu as effective as possible. Certainly there are no problems between me and Conte: he commented on a match for Italian TV, so it was his right to express an opinion."
