Just days before Paris Saint-Germain touch down in the Spanish capital, Zinedine Zidane's Real Madrid have the chance to boost their fragile confidence when they face Real Sociedad in La Liga on Saturday. The reigning European champions have been shipping a worrying number of goals in the build-up to their Champions League last-16 showdown with the likes of Neymar, Edinson Cavani and Kylian Mbappe. Zidane's side have kept just one clean sheet in their last eight outings, and they could pay a heavy price for any goals conceded against the French giants in next Wednesday's match at the Santiago Bernabeu.
