"We haven't heard from each other. It's a personal conviction," Mourinho explained in an interview with Telelombardia.
"It seems to me that he has had a great season and he has no reason not to be happy with us.
"After Real Madrid's huge transfer deals, I do not believe there will be a crazy market.
"No one will meet Ibra's true value on the market, no one will pay the same figure for Cristiano Ronaldo. But in football you never know.
"At the moment, if you want to make two teams with Cristiano Ronaldo and Kaka and all the other champions it doesn't seem possible to me that you can do much more."
Mourinho then revealed how his objectives coincide with rather than differ from those of Ibrahimovic.
"I too want to win the Champions League, but four teams fight for the Scudetto, two for La Liga and three for the Premier League while in the Champions League 12 teams fight for it, and for this reason, it's not easy."
