Manchester United center back Harry Maguire has been offered to Inter. The England international, who missed out on his country's World Cup roster, could leave Old Trafford this summer.
Meanwhile, Man Utd are looking at five strikers to bolster their squad ahead of their return to the Champions League. Galatasaray's Victor Osimhen is the dream target at the top of a shortlist which also includes Robert Lewandowski, Dušan Vlahović, Eli Junior Kroupi and Jean-Philippe Mateta.
Competition for Kroupi's signature could come from Bayern Munich, who are interested in the Bournemouth forward after missing out on Anthony Gordon.
Arsenal have not ruled out selling club captain Martin Ødegaard this summer and are already planning to replace the Norway international with Barcelona's Dani Olmo.
As for potential incomings, Arsenal are plotting a move for Atalanta goalkeeper Marco Carnesecchi, but will have to pay at least $47 million (€40 million, £35 million) to get a deal done.
Tottenham Hotspur's hopes of keeping midfielder João Palhinha after his loan from Bayern Munich have been dashed after he agreed personal terms over a return to Sporting CP.
Bodø/Glimt striker Mikkel Bro Hansen, 17, is being tracked by Chelsea, Manchester City, Newcastle United, Barcelona, Ajax and Juventus.
Aston Villa center back Tyrone Mings has emerged as a target for Turkish outfit Beşiktaş.
A budget of $336 million (£250 million) will be given to incoming Man City manager Enzo Maresca, who is planning moves for Chelsea midfielder Enzo Fernández, Nottingham Forest's Elliot Anderson and Tottenham right back Pedro Porro.
Barcelona are looking to pay just half of their $35 million (€30 million, £26 million) option to sign Marcus Rashford permanently from Man Utd this summer. The Red Devils have previously refused to negotiate.
Real Madrid have made a formal offer to sign Paris Saint-Germain midfielder João Neves worth around $140 million (€120 million). Club president Florentino Pérez and incoming manager José Mourinho are both eager to get a deal done.
Neves has asked his agent, Jorge Mendes, to find him a move to Real Madrid, but PSG are unimpressed by his stance and are not considering a sale.
Mourinho has also made it clear he wants young midfielder Nico Paz re-signed by Real Madrid this summer, even though the Argentina international would prefer to remain with his current side for at least one more season.
A move to Barcelona for Chelsea left back Marc Cucurella will only be possible if the La Liga champions can raise funds through the sale of Jules Koundé.
Ansu Fati has accepted a permanent move to Monaco after a successful loan spell. The deal will earn Barcelona around $13 million (£11 million).
