#2 Jan Oblak
The Slovenian has been labeled as one of the best goalkeepers in the World right now due to his consistent and solid performance for Atletico. Everybody knows that Atletico Madrid are one of the strongest teams when it comes to defense; thanks to Oblak's shot-stopping abilities.
The 26-year-old has all it takes to become an impenetrable wall for Real Madrid as he has been equally excellent in stopping both long and close-range shots for Diego Simeone's men. Oblak has recorded twice the amount of Courtois's clean sheets and conceded 9 fewer goals than the Belgian so far this season.
However, Real Madrid would need to dig deep into their pocket to secure the Slovenian's service. Several clubs including Manchester United have also chased the Atletico star and could be a major competitor for the Blancos.
