It's no secret that five-time Ballon d'Or winner and Portugal skipper Cristiano Ronaldo, 36, is not happy at Serie A side Juventus, and recent reports claim that he's keen to rejoin Spanish giants Real Madrid.
However, Ronaldo's switch to Madrid is largely dependent on French striker Kylian Mbappe's future.
Real Madrid President Florentino Perez, who hasn't had a great relationship with Ronaldo in the past, is keen to sign the PSG striker, which could prove to be the biggest stumbling block in the Portuguese's plans.
But if PSG refuse to sell Mbappe to the La Liga club, Ronaldo's chances of making a return to Real Madrid may improve, especially as Italian manager Carlo Ancelotti – who has managed Real before – is back in charge of the Madrid side. Ancelotti and Ronaldo share a great bond.
"I want to work with him again. He's like a big teddy bear, he's really sensitive and is a great guy. He would speak with us every day, but not just with me, with all of the players," Ronaldo said last year. "He had great fun with us. He's a great person and my only wish is that every player gets the chance to work with him because he's such a great guy and a fantastic coach."
CR7, as Ronaldo is popularly called, joined the Spanish giants after signing a then world-record $130 million deal in 2009 before ending his stint with them in 2018.
During his time in Spain, he won four UEFA Champions League titles.
He also accomplished a number of other personal milestones and set several records in Madrid, including four Ballon d'Or awards, cementing his place as one of the greatest footballers in history.
