Real Madrid coach Carlo Ancelotti has insisted that contract talks with Cristiano Ronaldo "won't be a problem".
The Portuguese forward, who has two years left on his current deal, has been linked with a return to Manchester United in recent weeks.
Meanwhile, Paris Saint-Germain are understood to be monitoring the 28-year-old's transfer situation.
"Everyone knows that he is a superstar and a great player," Ancelotti is quoted as saying by ITV Sport.
"The most important thing for the club is that a player of his quality shows the utmost professionalism.
"I am not responsible for the renewal of his contract, but it won't be a problem."
Ronaldo scored 50 goals in all competitions for Madrid last season.
