3. Jan Oblak
The best thing to replace one Atletico Madrid goalkeeper is to get another one. Prior to this season not many would have heard about Oblak but at only 22-years of age, he broke into the limelight thanks to his brilliant performance against Real Madrid in the Champions League. Oblak has been a great player for Benfica before his move to Atletico and like Courtois and De Gea, he has been groomed for greatness. Young and strong, he could provide the cover for Victor Valdes for one season before taking over the gloves next season.
