Gareth Bale, the well known forward of Real Madrid is an extravagant player. In the match against Atletico Madrid, he scored the third goal of the match, concluding the game with a 3-1 win for his team.
This goal also rounded up his goal count for Real Madrid to 100. This is a great milestone for any player to achieve, so Bale wanted to portray his excitement and enjoy that very moment.
Bale raised a bent arm and hit it with his other hand. However, that very gesture is considered offensive in Spain. La liga took this gesture seriously, and now is asking the Spanish Football Federation (RFEF) to file a sanction against him
