Real Madrid vs Barcelona: Five things to look out for in the double El Clasico week

4) The wonderkids - Vinicius Jr. vs Ousmane Dembele

Vinivius Jr gave Barcelona a hard time in the first leg

No one in Europe had heard about his name when he signed for Real Madrid from Brazilian club Flamengo. His exploits weren't really unheard of and he was snapped up by the Los Blancos in 2017.

Fast forward through 18 months and Vinicius Jr. has already cemented his place at left- wing of the Real Madrid starting XI with some really amazing performances. He is never afraid to dart in at defenders and he can pull a rabbit out of a hat by changing the game in the flick of an eye. He has really come of age and what's more, he is only 18. He would definitely be looking to dazzle against Barcelona.

Ousmane Dembele's transfer from Borussia Dortmund to Barcelona was a topic of huge debate because of the staggering sum of 105 million euros that was paid for his services. Initially, he failed to impress and had to sit out due to long injury spells, but he has slowly grown into the Barcelona team.

There is an uncertainty about the kid because he can devastate opposition defenses at will and open up the game with a deft through pass. He has scored 13 goals so far and assisted six times this season. Each time he is on the field, he contributes to the team's cause. He could be Barcelona's X-factor as they go up against their eternal rivals.
