Chelsea have rebuffed Bayern Munich's attempt to sign forward Christopher Nkunku on loan.
Chelsea and the player would prefer a permanent move and talks are ongoing.
The Blues want to offload Nkunku, Nicolas Jackson, Carney Chukwuemeka and Ben Chilwell among others before bringing in a wide player and an attacking midfielder.
Manchester United's Alejandro Garnacho, Xavi Simons of RB Leipzig and Manchester City's Savinho, who is a target for Tottenham, have been discussed to varying degrees.
The London club made an underwhelming start to the Premier League season as Crystal Palace ground out a goalless draw at Stamford Bridge on Sunday.
