Manchester United are maintaining their stance that Cristiano Ronaldo is not for sale this summer. The Portugal international arrived on Tuesday with his agent, but is yet to begin preseason training with the Red Devils. The Portuguese international has been linked with several other Premier League clubs and has been absent from the club's recent tours of Australia and Thailand. United have reportedly opened talks with a number of other clubs over the summer, but are not letting the Portuguese winger leave the club.Eric Bailly wants to stay at Manchester UnitedThe Belgian international has been heavily linked with a move to Lyon, but has been unable to impress at Manchester United this season. Although he has made a handful of substitute appearances, Bailly has failed to cement a regular starting spot for the Red Devils. In six seasons, he has made just 70 appearances for the Red Devils, scoring once. However, his desire to stay at Manchester United and fight as a team has not been quashed.The Frenchman has recently told Manchester United that he wants to stay at the club and fight as a team - and it is not the end of the world if he is offered a contract with another club. The club is also willing to sell Bailly, but the current situation means that he has no option but to fight for his place at Old Trafford. With so many potential targets in the summer, the club will need to be open to offers. Despite his recent struggles, the Frenchman has made 113 appearances for the club since 2016.The former Everton man has impressed at Manchester United during pre-season, and he's keen to continue his association with the club. However, Manchester United's recent success has meant that they already have too many centre-backs, and Roma are keen to sign Bailly on loan. However, the club's asking price of EUR15m has been questioned, but a loan deal seems like the best option for Bailly.While Bailly has struggled under Solskjaer, the Reds are keen to sign him, and he is set to hold talks with the manager. Although his contract runs out in 2020, the club has the option of extending it by two years. In the meantime, he hopes to impress under Ole Gunnar Solskjaer and fight for his spot. This could be the first step toward a new contract at Manchester United.Bailly is a fan favorite. He was in the African Cup of Nations, but the team needed players and Bailly was unable to participate. The defender had not played since Dec. 30, but his injury has limited his availability. Varane's arrival has created another obstacle for Bailly. In the meantime, he may have to compete for a starting place with Maguire.Cristiano Ronaldo wants to leave Old TraffordAfter just one season, Cristiano Ronaldo wants out of Manchester United. The team has been unable to compete in the Champions League and is no longer in good enough shape to play against the best teams in England. Last season, Manchester United finished sixth while rival Manchester City took first place. Ronaldo has been in Portugal with his family. But he has not spoken publicly about his desire to leave United. Here are the reasons why.First, he is unhappy with the contract. The Portuguese international earns PS480,000 a week and has been in the United camp for several years. United have an option to extend his contract until 2024. This would allow him to leave before the end of next season and help speed up the club's rebuilding process. The club have warned Ronaldo not to leave, but he has chosen to wait until five weeks before the new season to signal his wish to leave.Second, the Portuguese international has a very strong emotional bond with Manchester United. He played at the club from 2003 to 2009, where he won three Premier League titles and one Champions League. Ronaldo is the all-time leading scorer in the Champions League with 45 goals. He has also won the Champions League five times and has not missed a season of Champions League play. If Manchester United do not win the Champions League this season, he will surely look for another club.As long as United can find a replacement for Ronaldo, they will have a hard time. United are already struggling in the transfer market this summer and have not made any new signings. Despite the problems, there is an opportunity for the club to strengthen its squad. But the time is not yet right for the Portuguese star to leave. If he leaves, it will be detrimental to the team's reputation.The Portuguese striker has also told the club he wants to leave Old Trafford if a'satisfactory offer' arrives. Although the club has yet to make a formal offer, the Portuguese forward is likely to leave the club when the transfer window opens in the summer. He returned to Manchester United last summer after spells with Juventus and Real Madrid. Unfortunately, the team have failed to break into the top four this season.Manchester United close to signing Lisandro MartinezAfter missing the Red Devils' pre-season tour due to personal problems, it seems like the Portuguese international is not for sale. However, the club are determined to hold on to him despite reports that he wants out. The Portuguese forward is expected to meet with Manchester United's top powerbrokers and manager Erik ten Hag this week. It is likely that the pair will find a solution to the Portuguese striker's dissatisfaction with Old Trafford.According to reports, Jose Mourinho has renewed his interest in Bailly, who was one of his first signings when he became manager of Manchester United last season. He joined the club from Villarreal in a PS34million deal. If Bailly stays at Manchester United, the two could reunite in Rome. However, Lisandro Martinez, who joined United from Ajax last summer, has reduced Bailly's chances to play.There is speculation that the Frenchman could leave Manchester United for Roma. This news is not surprising, as Bailly spent two years with Mourinho at Villarreal and has been struggling for fitness and form. But, it is not yet confirmed whether the manager will sell or not. The Portuguese manager has also refused to sell Cristiano Ronaldo to another club, so the Frenchman is keen to keep Bailly at Manchester United and fight for his place under Erik ten Hag.Despite being linked with a move to Juventus, the Red Devils have ruled out selling the 'Juventus target' to the Premier League. Though Martial had a troubled Old Trafford career, he is well placed to start under new manager Erik ten Hag. However, Ronaldo will be up against a stiff challenge if he is to get back in the starting XI against Brighton on Tuesday. The front man's availability may be the reason behind the speculation over his future at Manchester United.In addition to being in a position to play in the Champions League, Bailly wants to remain at Old Trafford. Despite being one of the best centre-backs in the world, Bailly is prone to recklessness. This has become an issue at Manchester United and has made him a liability. If Bailly is sold, he could leave in January, but he wants to stay and fight as two.United running out of patience in pursuit of Frenkie de JongThe Dutch defender's future appears to be in the hands of Manchester United. The club has been patient enough to allow him to negotiate a new contract. The current one expires in 2026, so it's unlikely the Dutch giants can convince him to leave. Meanwhile, Barcelona have already announced a sale, but they had hoped for other suitors.Although United have been patient enough to offer the Dutch defender one more week, they cannot match Barcelona's offer. De Jong has recently become engaged and bought a house in Barcelona, so it's likely that the Spanish club will do everything they can to keep him. Manchester United will therefore have to find a less expensive alternative. In the meantime, Chelsea could be watching.Despite his recent move to Barcelona, De Jong remains reluctant to leave Barcelona. According to Diario Sport, the Dutch giants and the Spanish club have recently been at loggerheads over a coveted striker. United chiefs may be tempted to look elsewhere before making the move. After all, it was the Dutch side who failed to sign Cesc Fabregas and are now at loggerheads over a potential deal.Manchester United have long hoped to strike a deal which reflected Barcelona's desire to sell. As a result, they have now agreed a fee of EUR55million with Barcelona. While United have had to wait until negotiations have settled, the Spanish club's lack of funds has meant the signing of De Jong has been delayed. This is partly due to De Jong's wage deferral in 2020, which will essentially be the price at which he would be eligible to join United.Despite their apparent lack of patience in the pursuit of Frenkie de Jong, United have also made another transfer target in Tielemans. The Belgium international is out of contract in 2023 and is available for PS25m or PS30m. Given his talents, a move to United for the Belgium international could make sense. However, United are unlikely to get the same value for the Belgian, but it would still make sense.
