Mateo Messi was very happy on Saturday. Leo Messi's son has done lots of jokes in the past on his father, his brother and even on Real Madrid!
The last thing he did was on the family's summer holiday. While the family were taking a photograph, he put his thumb down during the picture.
But Mateo was more serious on this occasion. His mother, Antonella Roccuzzo, published a video on Instagram in which she showed how Mateo celebrated Messi's goal for Barca against Granada.
The Argentinian striker extended Barca's lead by scoring with a free-kick and his children celebrated it in style: jumping, shouting and smiling.
