Neymar (PSG)
One of the biggest names and brands in world football, Neymar seems the ideal Galactico figure that Real Madrid president Florentino Perez likes to have at his club.
The Brazil international only joined PSG last summer, however, so could prove a tricky purchase, and a controversial one as well due to his Barcelona connections.
Still, in terms of skill and goal threat, Neymar would be another ideal candidate to fill the void left by Ronaldo at the Bernabeu.
Kylian Mbappe (PSG)
A young player who looks set to be a star of the world game for many years to come, Kylian Mbappe has shown himself to be the real deal in the last couple of years.
After his remarkable rise at Monaco, Mbappe moved to PSG last summer and would now be the perfect long-term replacement for Ronaldo at Real Madrid.
This would no doubt be another ambitious deal, but there may be few better than the France international to give Madrid fans genuine optimism that they could ever land a player good enough to achieve what Ronaldo has in the Spanish capital.
