#4 Real Madrid
In what would be a very bold move, Oblak could end up between the sticks for Atletico's arch-rivals. While this may be the most unlikely scenario, it can't be ruled out that both parties would be interested in a deal.
While moving directly from Atletico to Real would be considered a mercenary move, it's undeniable that Los Blancos are the more successful of the two Madrid teams. Should Oblak feel the desire to start winning trophies immediately, Real Madrid is the place to be.
For the three-peat European champions, Oblak would solve an issue that has been lingering at the club for several years. While the need for a goalkeeper is well-known to everyone related to the club, their seemingly endless (and so far fruitless) pursuit of Manchester United's David de Gea has been delaying the problem for years.
As Madrid's patience with De Gea wears thin, Oblak could be on a list of potential secondary targets for the European Champions, that is supposedly headed by AS Roma's goalkeeper Alisson Becker.
