Aston Villa goalkeeper Emiliano Martinez has taken a swipe at the officiating during his side's humbling defeat at former club Arsenal on Tuesday night.
Villa had come into the match looking to move level on points with the Premier League leaders and strengthen claims they could be a contender in the title race.
Unai Emery's side, however, came unstuck in the second half as the returning Gabriel Magalhães opened the scoring three minutes after the break, with Martinez arguably at fault for the goal, spilling the ball under pressure following a corner.
