Inter Milan president Massimo Moratti insists there are no plans for Jose Mourinho to return to the club.
Stories have emerged in the Italian press in recent days suggesting Mourinho could head back to the San Siro at the end of the season after Inter suffered four defeats in five games in all competitions.
Captain Javier Zanetti had said he would be happy to see the Portuguese back at the helm, but Moratti said: "I have read the stories in the papers, but there is nothing with Mourinho."
Even if there is no prospect of a return, Leonardo's future is certain to be the subject of intense speculation as a result of the recent run of form, but Moratti insists he still has faith in the coach.
"It's undoubtedly a moment of crisis owed to physical and mental tiredness," he said. "We weren't at our best when we had to be. The question of Leonardo's future hasn't changed a lot. He was making a fantastic effort until the game against Milan.
"We expected the maximum then. Instead perhaps the biggest mistake was sending the players on international duty. We were convinced that we were still in great form. Instead we were very tired."
He added: "Leonardo is trying to do what is necessary and for me he is doing well, but naturally it's not very easy to stop a situation of this nature. We hope that he gets back to doing things well, even if we need a good week's rest."
Meanwhile, AC Milan owner Silvio Berlusconi has warned Inter that their recent success is coming to an end this season.
"You've been great," Berlusconi said. "The treble was an historic achievement and Mourinho was extraordinary, but now we win. Last year we made Inter win everything. Now that's enough."
