Diego Simeone went full Diego Simeone on the touchline as Atletico Madrid took a giant step towards the Champions League quarter-finals with a 2-0 victory over Juventus.
Goals from centre-backs Jose Gimenez and Diego Godin stunned Juve in the second half to give Atletico the advantage heading into the second leg of the last-16 clash in Turin.
The Spanish club were denied a penalty and Alvaro Morata had a goal disallowed during a frantic period before Gimenez's opener and emotions spilled over the dugout.
Simeone lost his damn mind and produced the most bizarre of reactions as Gimenez finally managed to break the deadlock with the scrappiest of goals at the Wanda Metropolitano Stadium.
The Argentine, whose team have twice finished runners-up in the Champions League under his management, grabbed his crotch while looking up into the crowd and screaming... as you do.
Totally normal celebration, this...

Incredibly, Simeone remains undefeated as Atletico Madrid manager against Italian opposition in the competition, winning five and drawing twice against Serie A clubs.
Even more astonishing, Kaka is the only player to score against Atleti since Simeone has been in charge.
