Kingsley Coman to Arsenal
The turnover in Arsenal's squad looks set to continue, with Unai Emery reportedly interested in the Bayern Munich winger. The Guardian claims the London club are targeting the 22-year-old Frenchman, but he will set them back £44 million if Arsenal want to make a move for him.
Tiemoue Bakayoko to Sevilla
Bakayoko struggled in his debut season at Chelsea, and he is now reportedly open to a move away from London. Sevilla made contact with the 23-year-old's representatives, and reports from Estadio Deportivo suggest the midfielder was receptive to the idea.
Arturo Vidal to Manchester United
Vidal has been linked with Premier League clubs for several years, but Bayern Munich are finally open to the idea of selling him, according to Bild. With new Bayern manager Niko Kovac possibly looking to renew his squad, the Chilean midfielder could be available for around £31m.
Rachid Ghezzal to Leicester City
Leicester may have lost one Algerian winger this window after Riyad Mahrez joined Manchester City, but they're looking to buy another. Manager Claude Puel helped to bring Ghezzal through the Lyon academy, and the 26-year-old might be available after a difficult first season at Monaco. Le10 Sport are reporting that Ghezzal could be available for just £4m.
Gianluigi Donnarumma to Chelsea
Donnarumma is one of three names on a shortlist that Chelsea have drawn up to replace Thibaut Courtois, who they are reportedly resigned to selling to Real Madrid. According to the Evening Standard, the 19-year-old is wanted by Maurizio Sarri, while the goalkeeper's club, AC Milan, are also interested in Chelsea striker Alvaro Morata.
