Jhon Duran has made a habit of coming off the substitutes bench and scoring for Aston Villa this season.
On Tuesday, the Colombia forward made his first start at Villa Park for 11 months and marked it with his side's second goal against Bologna in the Champions League.
Duran's celebrations were cut short when he was immediately replaced by Ollie Watkins, and he showed his displeasure by kicking the back of one of the dugout seats in frustration.
Unai Emery is not too upset with Duran's reaction, however.
Duran now has seven goals in all competitions while Watkins has five - two forwards delivering goals as Villa enjoy one of their best starts to a season for years.
