Cristiano Ronaldo's sister Katia Aveiro took a swipe at Gerard Pique after FC Barcelona's El Clasico defeat on Saturday.
The defender has become quite active on live streaming app Periscope of late, and, before the weekend's big derby, predicted a 2-0 win for Barcelona in a video clip with international teammate Cesc Fabregas.
Aveiro took to Twitter soon after the final whistle of the game, which Real Madrid won 2-1, and hit out at Pique after her brother had scored the winning goal.
"My question is if today Gerard Pique will make a Periscope. Everything started with you, no? #WhoKnows" she tweeted.
The Spain international has always been quick to troll Los Blancos on social media in the past, and back in December, the defender could not contain his excitement when Real were kicked out of the Copa del Rey for fielding an ineligible player.
Do you think the dig was needed, or was the victory enough to hurt Pique? Have your say in the comments section below.
