According to Cristiano Ronaldo's new club Al Nassr, his contract includes no commitment to support Saudi Arabia's ambition to host the 2030 World Cup.
According to reports, Ronaldo will earn 200 million euros (£177 million) to promote the bid on top of his yearly income of £177 million.
But the club said his deal "does not entail commitments to any World Cup bids".
"His main focus is on Al Nassr and to work with his teammates to help the club achieve success," they added.
The Portugal captain joined the Saudi-based club as a free agent last month after quitting Manchester United in the aftermath of a contentious interview in which he criticised the club.
He will make his Al Nassr debut against Ettifaq on 22 January, although he might play in an exhibition match against Lionel Messi's Paris St-Germain beforehand.
Saudi Arabia is allegedly mulling a combined proposal with Greece and Egypt to host the 2030 World Cup.
