Off the back of his truly sensational 360-degree video at the FA Cup Final, Mateta was back at it at the Leipzig Stadium last month, having a mere half-an-hour beforehand scored the goal which set Crystal Palace on their way to collecting the UEFA Conference League trophy.
The result? A riotous mix of chaos, dancing, laughter – and an insight into what it's like to share a celebration with the joyous Palace No. 14, who earlier this week also made his first-ever World Cup Finals appearance for his country.
It's truly a video you won't want to miss: watch on Palace TV below, now.
Happy birthday, JP!
