4. Source of goals for Real
One reason for Real Madrid's wretched run has been their goal drought. The Post-Cristiano Ronaldo period has been tough on Los Blancos. They had to suffer their worst run without scoring a goal. A run which stretched for 4 matches. They finally broke it when Marcelo scored, but they have scored only 2 more since then and the Brazilian left-back scored one of them. For a team that contains world-class attackers, the lack of goals is a real concern.
Los Blancos will be relieved that Benzema ended his drought with a goal against Plzen and will be hoping he scores again come Sunday. Bale will also be under the microscope and has the opportunity to show everyone he is Real's main man in Camp Nou. Asensio is another threat who could give Barca's backline headaches with his pace and dribbles. Barcelona will be keen to lock him down after he made them suffer in last year Super Copa.
