The football world will witness the latest episode of the Madrid Derby this Sunday as Real Madrid welcome neighbours Atletico Madrid to the Santiago Bernabeu. Ever since Atletico's resurgence under Diego Simeone, this has been a fiery affair, to say the least.It's also a battle between 2nd and 3rd with Atletico going into the game four points ahead of Real Madrid. Thus, it is a game that Los Blancos simply cannot afford to lose.They have only a one-point lead over fourth-placed Valencia and Zinedine Zidane's men will be wary of the implications of a defeat this week.The reverse fixture, in November, saw the two sides play out a tightly-contested 0-0 draw.So, ahead of the showdown, we look at an XI comprising players from both teams:FORMATION: 4-3-3Goalkeeper: Jan Oblak (Atletico Madrid)Oblak is one of the best in the worldDespite Keylor Navas showing his heroics between the posts of late, Jan Oblak is a more stable option.The 25-year-old has escalated into one of the top goalkeepers in the world, partly because of Diego Simeone's affinity towards defensive solidity and also because of his stunning performances.This season he has been in between the posts 38 times for Atletico and has kept 24 clean sheets, which is sensational. He recently completed 150 appearances for the club and has kept 86 clean sheets, conceding only 90 goals. Quite brilliant.
