Barcelona stuck three past Real Madrid at the Bernabeu and emphasised their dominance at the top of La Liga with the win.
The Catalan side are now 14 points clear of Real in the table thanks to second-half goals from Luis Suarez, Lionel Messi and Aleix Vidal.
The right-back could not resist trolling Cristiano Ronaldo after the final whistle and was snapped mocking the Real star in Barca’s post-match snaps.
Andres Iniesta and Suarez both shared the photo of the team enjoying the victory and Vidal can be seen imitating Ronaldo’s iconic goal-scoring pose.
“The best way to end the year! Great team, Forza Barca,” Iniesta captioned the photo.
And Suarez was equally pleased with the result, adding: “Let’s go. Come on, Great teamwork.”
Vidal’s joke pose seemed to go unnoticed by his team-mates but the fans were certainly loving it as it began to circle on social media.
“LMFAO Vidal is actually imitating Ronaldo’s flexing-abs pose,: one supporter wrote on Twitter.
“Vidal trolling Ronaldo,” another added.
“Why is Aleix Vidal obsessed with Ronaldo? lol,” a third fan wrote.
