Real Madrid have made Chelsea goalkeeper Thibaut Courtois their main target between the sticks and his transfer is set to start a merry-go-round.
Courtois is keen to return to Madrid, where his wife and children still live while he was on loan at Atletico.
But the Blues will then move for either Roma No.1 Alisson - who is the subject of a world-record £67m bid from Liverpool - or old favourite Petr Cech.
Arsenal are open to selling Cech to provide manager Unai Emery with the funds needed to continue rebuilding his squad.
Leicester ace Kasper Schmeichel is also being considered to join Maurizio Sarri’s squad.
The 31-year-old is said to have three years left on his Foxes contract, but could be lured by the chance to play European football.
AC Milan’s 19-year-old Italy No.1 Gianluigi Donnarumma has been linked to a move to Stamford Bridge too.
