Despite Mancini scoring the winning goal in a crucial 1-0 victory over the Old Lady, the Special One seemed unfazed by it all!

Jose Mourinho is the gift that keeps on giving!

Sunday saw Italian giants Roma and Juventus lock horns in a crucial fixture, with I Giallorossi securing a much-needed 1-0 victory. While several key things happened on the pitch during this showdown, ranging from Gianluca Mancini's brilliant winning goal to Moises Kean getting sent off one minute after being subbed on, it is Jose Mourinho who has gone viral.

It was less than a week ago when the Special One was shown a red card in his side's 2-1 loss to Cremonese. However, while the Portuguese tactician stole the show once again, it wasn't due to anything controversial. Rather, it had to do with his hilarious reaction to his side's only goal of the game.

This moment was shared on social media by Roma's official Twitter page. During the 53rd minute of Sunday's tie, which is when Mancini pulled off his stunning effort, Mourinho was stood alongside Tammy Abraham and one of his assistants. The Special One was writing down instructions on a piece of paper in preparation for the Englishman's introduction.

However, the manager paused for a second to look as Roma's attack became promising. Seconds later, Mancini blasted the winner past Wojciech Szczesny, sparking celebrations from the Giallorossi dugout. Even Abraham, who was subbed on a while later after this goal, ran onto the pitch in celebration.

What about Mourinho? The 60-year-old did not even flinch. Instead, he calmly went back to writing down instructions without even a smile while everyone else was jumping up and down, celebrating the goal that would secure the home side the three points. Check out this moment in the video below.

What makes things even better was just how important this result was. With AC Milan slipping up away to Fiorentina on Saturday, losing 2-1, Dybala and Co. managed to leapfrog the Scudetto holders to enter the top four — their advantage over the Rossoneri is simply due to goal difference, though.

Mourinho's men are currently in fourth with 47 points, level with Milan but only three behind second-placed Inter. Next up for the Serie A heavyweights is their interesting UEFA Europa League showdown with Real Sociedad, with La Real visiting the Italian capital for the 1st leg of this round of 16 tie.
