A passionate Chelsea FC supporter, Kevin Pietersen, has made an extremely bold request to the Premier League club: Sign Cristiano Ronaldo. Manchester United winger Yuvraj Singh was brutally trolled by the defender after his tweet, and this has sparked a huge debate about Ronaldo's future. The Portuguese international, frustrated with the lack of activity in the transfer market, has made it clear that he wants to leave the club.Kevin Pietersen wants Chelsea to sign Cristiano RonaldoFormer England captain Kevin Pietersen has tweeted that he wants Chelsea to sign Cristiano Ronaldo this summer. The player is currently on the transfer list with Manchester United, but it is unclear if he will stay there after requesting a free transfer. Pietersen is a huge Ronaldo fan and said in a tweet that he wants Chelsea to sign the Argentine superstar this summer.The England cricketer turned 42 today and shared a birthday message on Twitter to the football superstar. The player is a Chelsea fan and he used their facilities during his career. He is keen to sign Cristiano Ronaldo, and it seems the new Chelsea owner Todd Boehly has met with the agent of the Portuguese superstar Jorge Mendes. The two men met in Portugal and discussed Ronaldo's future and possible Chelsea move.Juventus have reportedly offered a deal to sign the Portuguese forward. The deal is understood to be worth more than £150 million, but if Ronaldo is a Chelsea fan, then it may be worth the effort. Ronaldo has already spoken to the club's new owner about his wishes, so Pietersen is right. He wants to sign Ronaldo as a birthday present. The Portuguese ace has been linked with a number of top European clubs, including Barcelona, and has made it clear that he wishes to leave Manchester United.Real Madrid have been linked with a move for Cristiano Ronaldo in the summer, as the former Manchester United forward is unhappy with the club's lack of transfer activity and has been in Spain and Portugal. Real Madrid have been in the race for the player in recent months, but have not yet been able to find the money to pay him. The player wants a deal in the same wage bracket as Lionel Messi and Neymar.Ronaldo's future at Manchester United is a hot topic of debateEver since the 4-0 loss to Liverpool, the future of Ronaldo has been a matter of much speculation. While United have repeatedly said that Ronaldo is not for sale, rumors are resurfacing. In the aftermath of the match, a photo of the Argentinian was shared on social media by Ronaldo and his close friends. The photo showed him smiling in front of a cliff-side backdrop. The future of Ronaldo at United is in doubt, as the club are set to miss Champions League football.The Argentinian has been linked with a move to Barcelona after the disappointing season he endured at Manchester United. The Barcelona midfielder has also been linked with a move to Juventus. While this transfer is not confirmed, the rumours suggest that Pogba is keen to leave United for a higher profile club. He also reportedly prefers playing alongside Lionel Messi rather than Cristiano, despite the latter's recent comments.The Portuguese superstar's future at Manchester United is under hot debate as the team's form has suffered and it has been difficult to convince the club's fans to sign him. In January, the club's manager Ole Gunnar Solskjaer announced his departure, but that was not the end of the Ronaldo saga. While the Portuguese is not a perfect player, he certainly is an outstanding player and one of the best players in the world. However, he is far from a finished product, and his recent dramatic outburst has only served to muddy the debate.Wayne Rooney is another player with an equally impressive record. Ronaldo is only 30 years old, but has the discipline to make a top-class player. He has scored 155 goals in 219 appearances for Manchester United - only Andy Cole has more Premier League goals than Rooney. Nevertheless, he is the star of the United team. So, there are plenty of debates on the future of Wayne Rooney, but this is unlikely to change the outcome.A big debate has raged over whether Manchester United should sign the Portuguese winger. Ronaldo has scored 145 goals in 261 matches for Real Madrid, but his lack of quality in midfield means that he cannot be the team's main man. A manager must play to the best of his player's abilities and maximise his potential. But if he does decide to leave, it's only fair to make the player more valuable to his team.Ronaldo has grown frustrated over lack of activity in the transfer marketCristiano Ronaldo has become increasingly frustrated with the lack of activity in the transfer market after joining Manchester United last September. After a dismal season in which they failed to make the Champions League, the club are expected to revamp their squad and Ronaldo was not happy with the lack of new signings. However, he has become increasingly frustrated with the lack of activity in the summer transfer window. The Italian winger wants to leave United as soon as possible and has expressed his desire to leave for another club.While the lack of movement in the transfer market has frustrated the Portuguese star, it is important to bear in mind that United fans are growing increasingly impatient with the situation. United manager Edgar Ten Hag, who is expected to return to Carrington this week, is also growing frustrated with the lack of movement in the transfer market. The irritated manager will want to keep Ronaldo happy as he is the only out-and-out striker at the club.Cristiano Ronaldo has reportedly grown frustrated over a lack of activity in the transfer market. Chelsea have been linked with Ronaldo but have refused to make an offer as the club can't afford the superstar. Meanwhile, top teams in the Champions League cannot afford to buy him. So Atletico Madrid are interested in signing the Portuguese. But if he does leave, he could be making a big mistake for the club.In addition to growing frustrated over the lack of activity in the transfer market, the Portuguese international has also been expressing doubts about his contract at Manchester United. As a result, the Portuguese star's future at Old Trafford will depend on how United conduct business in the transfer window. If United fail to make a big splash in the transfer window, Ronaldo may yet stay at Old Trafford.Manchester United are in need of reinforcements and have five days left before pre-season. Erik ten Hag is reportedly in talks with Barcelona regarding Frenkie de Jong. Besides a midfielder, they have also been linked with Antony, who has worked with Paul Pogba at Ajax. But United are struggling to make a signing this summer. There are rumors that Ronaldo will leave the club.Ronaldo wants to leave Manchester UnitedCristiano Ronaldo has delayed his return to the first day of pre-season training at Manchester United. The Portuguese international has family commitments and is unlikely to fly to Thailand on Friday. United will also travel to Thailand and Australia during the pre-season tour. Manager Erik ten Hag is relaxed about Ronaldo's future. However, he is under no illusions that the former Portugal international will stay at Old Trafford.If the Portuguese international were serious about leaving, he would have made his intentions clear well before the end of last season. This would have forced a decision on United and Ten Hag but both parties have failed to communicate effectively. As a result, both parties are in a race against time to secure a replacement for Ronaldo and strengthen the squad under Ten Hag. If United and Ronaldo fail to act quickly, a major transfer could happen this summer.There are several possible buyers for the Portuguese star, with Chelsea and Bayern Munich reportedly keen. The club has been aware of Chelsea's interest but have yet to make a formal offer. Despite the interest in Ronaldo, the club is wary of losing a world-class star. It would be a huge blow to the club if Ronaldo is unable to stay at United. In addition to Manchester United, Ronaldo's contract expires in the summer of 2023, which makes him a hard target for other teams.Juventus have been linked with a move for Ronaldo. However, a move to Bayern would be the best option for the Portuguese superstar. The club has been in the market for a striker for some time and have recently made no additions. The German club has been looking for a replacement for Robert Lewandowski and could be the perfect option for him. As long as he is given a suitable offer, Ronaldo is sure to remain a sought-after player.Ten Hag does not expect to sign a new forward this summer and thought he could put off the search until January. That said, the news that Ronaldo wants to leave Manchester United has created a lot of uncertainty. Having lost both Darwin Nunez and Erling Haaland to Manchester City in the summer, United have no guarantees that Ronaldo will find a new club in the coming months. If Ronaldo does leave, it would be the biggest mistake of Ten Hag's managerial career.
