Brentford took the lead through Keane Lewis-Potter's strike at the stroke of half-time but Alex Moreno brought Aston Villa back into the game in the second-half before Ollie Watkins netted an 85th-minute winner.
Right after scoring the goal at the Gtech Community Stadium, the English striker pointed his finger towards a Brentford fan and did an animated celebration which evoked hostile reaction from the home fans towards the player for the remainder of the game.
