2) The return of Sergio Ramos
This man has seen it all and has been through all of Real Madrid's highs and lows in the last 13 seasons. From being a decent defender who showed a lot of promise when he signed from Sevilla to becoming one of the best center-backs in the modern game, Sergio Ramos is the real leader of the pack.
Whenever the Los Blancos are in need of a goal and the opposing defense is proving too difficult to break down, the majestic defender comes forward and heads in a corner with perfect precision. Madrid fans still swoon to the equalizer in the final of the 2014 UEFA Champions League against Atletico Madrid.
Ramos has the bad reputation of collecting red cards for some rash challenges. However, the Real Madrid captain is back against Barcelona after sitting out in the last game against Levante due to suspension. His return could be a potential cause of worry for Barcelona because there is no player who can step up to a big occasion more than him.
