Nasser Al-Khelaifi has dismissed reports that Paris Saint-Germain have already signed Thomas Tuchel to a contract.
Multiple reports have indicated Tuchel already has a deal in place to replace Unai Emery as manager.
Tuchel left Borussia Dortmund at the end of last season.
"If we had signed with someone, we would have announced it to you," Al-Khelaifi told Canal+. "Today we have a coach who was on the pitch. We are very honest; we have a coach today who works with us, with a contract until the end of the season.
"Let's be positive tonight, we've done a lot of positive things. We're champions, it's a wonderful thing, I thank everyone.
"And the season is not over yet, there is the cup to win. The Champions League is our big goal, but it's not easy. We work hard, but the other clubs do it too. We are very proud today."
