Luka Jovic, Eden Hazard, Gareth Bale and Mariano Diaz could all reportedly leave Real Madrid this summer.
Kylian Mbappe is expected to arrive at Bernabeu from Paris Saint-Germain at the end of the season, while Los Blancos are still said to be firmly in the picture for Borussia Dortmund's Erling Braut Haaland.
Carlo Ancelotti's side will need to move players on in order to make room in the squad, and according to Defensa Central, four forwards are likely to leave the club ahead of next season.
The report claims that Bale - out of contract this summer - will leave on a free transfer, while Jovic, Hazard and Mariano are expected to be on their way out.
Jovic still has more than three years left to run on his contract at Bernabeu, while Hazard has a deal in the Spanish capital until June 2024.
Mariano's deal is due to expire next June, and the 28-year-old has struggled for action this season, making just seven appearances in all competitions, failing to find the back of the net on a single occasion.
