The Serbian copied the Cristiano Ronaldo trademark celebration this evening.
Tomorrow night the Ballon d'Or award will be handed out to one of Lionel Messi, Manuel Neuer or Cristiano Ronaldo, with the latter the overwhelming favourite.
The Real Madrid forward has been sensational for the past 12 months and of course it all started to come to the fore at Manchester United. Ronaldo won his first Ballon d'Or whilst a United player in 2008 during his wonderful six year spell at Old Trafford.
Of course one of the iconic moments of that spell was his trademark goal celebration. Ronaldo would often rip his shirt off and flex his muscles to celebrate his goals.
Today, that celebration was emulated at Old Trafford, but unfortunately not by a Manchester United player.
Instead it was Serbian midfielder Dusan Tadic who celebrated in the style of the £80 million forward.
The Southampton star, who ironically left his shirt in the dressing room before being subbed on, scored the winner after Graziano Pelle's strike rebounded off the post into his path.
He stripped down and did the Ronaldo flex in front of the Old Trafford faithful, in a troll that likely left them even more despondent at the fact Southampton had just overtaken United in the Premier League.
