Barcelona teenager Gavi attempted to troll Real Madrid's Toni Kroos on Instagram following El Clasico - but immediately deleted his post.
Madrid ran out 3-2 winners in a thrilling contest on Wednesday evening to set up a Spanish Super Cup final with Athletic Bilbao.
Barcelona came from behind twice to level the scores but Federico Valverde's goal in the first period of extra time settled the game.
Gavi battled Kroos in the heart of midfield and managed to leave the World Cup winner floored in one passage of play.
The 17-year-old posted an image of it to his story with no caption, just himself darting away from Kroos.
It did not stay up for long however and it has now been deleted, probably because Xavi's side ended up losing.
He was probably hitting back at a picture Kroos posted last year, after Real Madrid's 2-1 away win in El Clasico when Kroos choose a picture of Gavi on the ground among 4 pictures he posted.
Gavi also made his Spain debut last year and Barcelona are desperate to improve his contract, with a number of top European clubs interested.
