Juventus survived one of their biggest domestic tests of the season on Sunday night as they left a tough Stadio Olimpico clash against Lazio with three huge points.
The hosts, who are aiming to get back into the Champions League qualification places, were fabulous in the first half and Juve would've been happy to go into the interval at 0-0.
Simone Inzaghi's men were rewarded in the 58th-minute when Emre Can accidentally headed a corner into his own net, but Juventus showed what they're about late on.
Joao Cancelo started the comeback when he rebounded Paulo Dybala's saved shot into the bottom corner - and then, up stepped Cristiano Ronaldo.
The iconic forward fired home a penalty to win it for Juve, and a video of his goal taken from inside the stadium shows how fans in Italy feel about him.
Cristiano secures big win for Juve at Lazio
Ronaldo failed to score from a penalty in the 3-0 win against Chievo but lined up alongside Dybala and Douglas Costa in attack in the Italian capital.
In truth, CR7 struggled to test Lazio 'keeper Thomas Strakosha during the game, but as he's done so often over the years, he eventually made the difference.
Cancelo was impeded in the box as he looked to latch onto a Federico Bernardeschi cross, and Cristiano made no mistake from the resulting 88th-minute penalty.
How the Stadio Olimpico reacted to Cristiano's penalty
The 33-year-old rifled the ball into the roof of the net and it led to a pretty interesting reaction from fans inside the Stadio Olimpico as he ran off in celebration.
Despite the home side, who share the stadium with bitter rivals Roma, being so close to a point against the champions, the "Siuu" chants are clear for all to hear.
Check out the video, recorded live at the ground, below:
Of course, there will have been Juventus fanatics at the game who joined in, but the loudness of the chant does suggest some home fans got involved too.
Why is this significant?
Ronaldo has only been in Italian football for just over six months since leaving Real Madrid, but it's starting to feel like fans of all teams in the country are appreciating the impact he's had.
The Bernabeu crowd shouted "Sii" for years whenever Cristiano scored, and the Allianz Stadium has replicated that for the five-time Ballon d'Or winner so far this season.
There was even a massive chant produced all the way in Saudi Arabia earlier this month after Ronaldo scored the only goal in the Supercoppa victory over AC Milan.
However, for the chants to be so loud, not at a home or neutral venue, but an away stadium in Rome, truly does sum up the magnitude of the man.
Cristiano now has 17 goals in 28 matches for Max Allegri's men this term and will hope to keep his decent form going next week in games against Atalanta and Parma.
