Look: Bale appears to direct obscene gesture toward Atletico fans

Gareth Bale may have contributed to a tense atmosphere at an already feisty Madrid derby.

After potting Real Madrid's third goal of the game, the Welsh forward appeared to celebrate by flexing one arm and slapping his bicep with the other toward the jeering Atletico Madrid fans.

Bale's goal was his 100th for Los Blancos in all competitions.

Real held on to defeat their city rivals 3-1, vaulting past Atletico for second spot in La Liga.
