#1 Andriy Lunin

Signed in the summer of 2018, Lunin was considered to be one of the most promising goalkeepers in the world, but then came the transfer of Thibaut Courtois which meant that the Ukranian was demoted to being the club's third choice keeper after the Belgian and Keylor Navas.
A loan move to Leganés followed but there too he could only make a total of 7 appearances in the 18/19 season. Still only 20, he has many years ahead of him to fulfil his potential, but if he returns to Madrid he'll possibly be the fourth choice there due to the promotion of Luca Zidane to the first team. Getting first team football is vital for him and he too needs to make the right move if he were to become one of the best goalkeepers in the world.
