Juventus forward Cristiano Ronaldo has been charged with improper conduct by Uefa for a goal celebration in the win over Atletico Madrid in the last 16 of the Champions League.
The 34-year-old appeared to mimic Atletico boss Diego Simeone, who turned to fans and grabbed his crotch during his side's 2-0 first-leg victory.
Ronaldo made the gesture after his third goal of his hat-trick in the return leg as Juventus won 3-0.
Uefa will rule on the case on 21 March.
Simeone was fined 20,000 euros (£17,000) for his celebration.
Juventus have been drawn to play Dutch side Ajax in the quarter-finals.
