Despite several reports linking Messi with Al Hilal, one of the top Saudi teams, club sources told AFP they had not been in direct contact with the Argentine's team.
"He is a player at the end of his career and he is not here only for football. He is here to secure international attraction for the kingdom," said the source following the Messi negotiations.
"The plan is not only Messi and Ronaldo, the plan is to bring glorious players like these two and also upcoming youth players who have a promising future.
"We want people to visit Saudi Arabia to watch football stars," the source added. "Who could imagine that local league matches would attract foreigners? It's just the Ronaldo impact."
PSG PROTESTORS
Messi, who turns 36 in June, has had two lacklustre seasons in Paris after a glorious era at Barcelona where he won four Champions League and 10 La Liga titles, and is still worshipped by the fans.
The record seven-time world player of the year, joining a mouth-watering attack featuring Kylian Mbappe and Neymar, scored just 11 goals in his first season as he helped PSG to a routine Ligue 1 title.
But PSG have got no closer to a coveted maiden Champions League victory, bowing out twice in the last 16 even with the illustrious Argentine in their line-up.
Frustrations boiled over last week when black-clad PSG protesters let off flares and sang hostile chants targeting the underperforming Messi, Neymar and Italian midfielder Marco Verratti.
The angry scenes contrasted with Messi's career-crowning moment in December, when he led Argentina to a breathless World Cup final victory over Mbappe and France in Doha to fill the biggest gap in his resume.
Saudi Arabia has held talks with Egypt and Greece about a joint World Cup bid, according to officials. In coming years it will hold the men's Asian Cup football tournament, the Asian Games and even the Asian Winter Games on artificial snow.
On Tuesday, state-owned oil giant Saudi Aramco announced quarterly profits of US$31.9 billion - more than three-quarters of the incomes of oil majors BP, Shell, ExxonMobil, Chevron and TotalEnergies combined.
