On Sunday afternoon, Barcelona fans were in a joyous mood as Real Madrid stuttered to their fourth straight draw in all competitions.
Just a few hours later, though, it was the supporters of Los Blancos who were left smiling after Barca succumbed to a surprise 4-3 defeat at the hands of Celta Vigo.
And, with the rivalry so fierce between the two Spanish giants, one Madrid cult hero couldn't help but rub salt in the wounds for the Barcelona faithful on social media.
Guti, a Real Madrid player for over 15 years who is currently a youth team coach at the club, wasn't about to let an opportunity to rile up the Catalan giants when given the opportunity.
Earlier in the day, he had had to sit back and take the abuse on Twitter as Madrid's current squad limped to a disappointing 1-1 draw.
And his tweet in the aftermath of Barcelona's loss made reference to that in true tongue-in-cheek style...
The message translates as:
"Thank you for your congratulations for Real Madrid's draw. It's a shame that I cannot say the same thing to you."
With over 15 years of service at Madrid as a player between 1995-2010, Guti wasn't exactly a popular figure amongst Barca fans. His trolling tweet suggests he quite enjoys playing the pantomime villain.
While Sunday's La Liga action saw Zinedine Zidane's side actually move one point further ahead of Luis Enrique's men, in truth, fans of both clubs don't have too much reason to smile right now.
Madrid may be unbeaten in the league and level with Atletico at the top of the table on 15 points. However, they haven't won since the 18th of September.
They're also dealing with an ever-increasing injury list, with the likes of Luka Modric, Marcelo and James Rodriguez all on the sideline.
Barcelona, meanwhile, will be more than a little concerned after conceding four goals against Celta Vigo.
With Lionel Messi still out injured with an ankle issue, the club have managed to retain their ability to score. Their issues with keeping goals out of their own net, however, are increasing.
