Real Madrid could be challenged by rivals Atletico Madrid in order Aymeric Laporte.
The Spain international is said to be keen on a move away from Saudi Arabia despite being linked with current side Al Nassr until 2026.
Los Blancos have shown an interest in a possible deal, but they did not meet the asking price of Al Nassr, in the region of 20 million euros.
Real Madrid hope that Laporte can cancel his contract in the Middle East, to force a move, but Atletico Madrid are also monitoring the situation with interest.
According to reports from The beach barLos Rojilancos are still on the hunt for another centre-back, despite bringing in Robin Le Normand from Real Sociedade.
It will be difficult for Laporte to end his Al-Nassr contract, as money is no object for the Saudi Pro League, but it remains his only realistic option to seal a move back to Spain this summer.
