What happened the last time Carvajal didn't mark Neymar?

UEFA announced on Tuesday that it has rejected 'Los Blancos' appeal against a two-match suspension for its Spanish defender, meaning that Carvajal will miss the first leg against Neymar and Paris Saint-Germain on 14th February.
To date, the 26-year-old and his former Barcelona rival have faced one another seven times in which the Madrid player has won on three occasions. In the other four, there has been one draw and three defeats.
However, there was one match where Carvajal wasn't available to play against the Brazil international and the result was not a pleasant experience for Real. Eternal rivals Barca dominated the 'El Clasico' posting a 4-0 victory at the Bernabeu, much to the annoyance of the home fans.
Neymar was a headache for then-manager Rafa Benitez, scoring one goal and opening the Madrid defence up with cutting passes, something which Zinedine Zidane will have to address in their upcoming fixture.
Benitez' solution was to bring in the Spanish defender but Zidane will not have that luxury following his suspension and will probably have to turn to Nacho as a reliable figure on that right-hand side.
Either way it will be a tough encounter as Real will have to contain the energetic performance of not only Neymar but PSG's entire attacking trio which also includes Kylian Mbappe and Edinson Cavani.
