There is a chance that Cristiano Ronaldo could be sold by Real Madrid this summer in order to meet Financial Fair Play regulations according to the Daily Mail - and Manchester United may well swoop for their former player.
Ronaldo left Old Trafford back in 2009 for a then-record £80 million, and has taken his game to another level in Spain. He's scored more than 250 goals in just five seasons at the Bernabeu, and is now just 71 goals short of Raul's all-time record for Madrid.
Last season may have been his best in a white shirt; the Portuguese superstar helped his team claim a record 10th European title by scoring a record 17 goals, including a penalty in the final against rivals Atletico Madrid. He also won the Ballon d'Or in January.
Sadly he couldn't replicate his best form at the World Cup because of a knee injury, and his lack of match fitness meant that Portugal were eliminated at the group stages.
Despite his continual excellent performances, there is a chance that he could be sold according to the Daily Mail. They say the've heard rumours that because Madrid have splashed out around £100 million on James Rodriguez and Toni Kroos, they need to sell up in order to balance the books.
It had initially been thought that the likes of Sami Khedira and Angel di Maria may be the ones to go, but as yet there have been no potential buyers forthcoming with concrete offers, and the Mail say Madrid could be looking at selling Ronaldo.
Of course if Ronaldo were to be made available then Manchester United would likely be interested in taking him back to Old Trafford. There was plenty of speculation last year that they were plotting an audacious move to bring him back, and executive vice-chairman Ed Woodward's recent quotes about being willing to shatter the transfer record will only encourage speculation. It would certainly take a world record fee to land Ronaldo, and he would most likely become the first £100 million-player.
Former Real Madrid president Ramon Calderon revealed earlier this year that Ronaldo could well look to return to Manchester United at some point as well.
Father and son
He told TalkSPORT in March: "I know when I signed him, he was saying that Manchester United for him has been like his house, he was quite happy there with the fans, with the club.
"At the time with (Alex) Ferguson, he considered him like a father, and everything for him in Manchester was perfect.
"But he wanted to come to Madrid and play for Real, and you never know, maybe at the end of his career he would like to come back to England and back to Manchester.
The former Manchester United man is approaching his 30's and was hindered by injuries towards the end of last season. Madrid may be tempted to sell up while he is at his peak value and before his performances dip.
However he signed a new five-year deal at the end of last year, and the fact that his commercial value is still so high means that Real Madrid are unlikely to even consider selling until next year.
