The transfer window is heating up, and the latest rumors are buzzing with excitement. Manchester United is reportedly exploring a move for Mateus Fernandes, a 21-year-old midfielder who impressed with his performances despite being relegated with West Ham. United's transfer hierarchy believes Fernandes has the potential to reach the heights of Declan Rice, and they are keen to bolster their midfield options. This development comes as a surprise, as Fernandes was only recently relegated with Southampton. However, it's not just United interested in Fernandes; Arsenal and Paris Saint-Germain are also believed to be keen on his services. West Ham, on the other hand, is determined to keep hold of Fernandes, but with the right offer, they might be swayed. Meanwhile, Marc Cucurella, a Chelsea left-back, is attracting interest from both Manchester City and Manchester United. The two clubs are said to be fond of the ex-Brighton ace, who has three years left on his contract at Stamford Bridge. Chelsea would be willing to listen to offers above £35 million, but it remains to be seen if either Manchester club will make a move. In other news, Kennet Eichhorn, a 16-year-old talent, has opted to reject Premier League interest and sign for Bayer Leverkusen instead. Eichhorn had been linked with both Liverpool and Manchester City, but his decision to stay in Germany is a significant one. Tottenham has also made a move, agreeing to a one-year deal with Ben Davies, a veteran player who has been with the club since 2014. Davies, while no longer a key player, is valued as a member of the Spurs squad and has signed an extension that will keep him at the club for a 13th year. Lastly, Arsenal is reportedly joining the race for Sandro Tonali, a Newcastle midfielder who has been linked with a move away from St. James' Park. Manchester United has been touted as the most likely destination, but now Arsenal is considered in the mix. Tonali was liked by Arsenal during the January transfer window, but nothing materialized, and he remained at Newcastle for the rest of the campaign. However, with Newcastle missing out on European football, it's suggested that the Magpies could be about to lose the Italian midfielder.
