Arsenal have attempted to tie down Ozil and Alexis Sanchez as their contract will soon expire but both resisted offers to stay with them.
When asked Mourinho if he would be interested in signing Ozil as a free agent, the Manchester United just grinned and declined to comment.
“Sometimes players they decide to go in this direction, which is a right that they have.
“They gamble, because imagine if one of these players has a big injury. Then probably next season he is without a club, but players have the right to do that.
“I don’t blame the clubs. The clubs they try, but the players have the right to go into this situation and in the end many times, it’s good for them.
“Sometimes they go on a free transfer and can get huge salaries. Other times, the clubs get to keep them, they make extra effort and offer very high salaries.
“I’m not speaking about Alexis or Ozil. I’m speaking about the general situation. Even some of us managers, we prefer to let the contract go until the last year and in the last year, we make the decision to stay, to leave.
“It’s a risk for everyone but sometimes the risk works. The important thing is that the players remain professionals and remain focused in the clubs where they are, and they give everything to the clubs until the last day.”
