Cristiano Ronaldo makes a habit of silencing his haters, big or small.

Despite boasting a career with four Champions League titles, five league championships, four Ballon d'Ors and a strong claim to GOAT status, the Portuguese certainly isn't immune to criticism.

It's certainly been the case this season with CR7 emerging from a wildly successful 2016-17 campaign in anomalously poor form and with just a single league goal to his name.

And those doubts - married to summer rumours of a Real Madrid exit - coaxed Ronaldo into a retaliatory rant back in September.

He defiantly responded: "People talk about me everyday all over the world, but I live for football and my family — not what is written about me in the press.

"Sometimes, it comes from Portugal, from Spain or from Germany.

"It is because the name Cristiano is world news. When you are great, people talk about you."

It's not the first time Ronaldo has come in for criticism during his career, though, and it came from an unlikely source back in 2013. 

None other than Sepp Blatter, FIFA president at the time, took a bizarre pop at Ronaldo during an appearance at the Oxford Union.

The Swiss was asked who he thought was the better played - Messi or Ronaldo?

He answered: "Messi naturally gets a lot of awards because he is a nice man, scores a lot of goals and plays well and the other one [Ronaldo]..."

Blatter then proceeds to get to his feet and produce one of the stupidest impersonates of Ronaldo you're ever likely to see - carrying out a bizarre march and salute to the bewilderment of the audience.

Furthermore, he then went onto to declare: "One spends more time at the hairdressers than the other," for which he was forced to apologise on Twitter.

He needn't have bothered, though, with Ronaldo producing the perfect reply just a day later as Real Madrid wiped the floor with Sevilla in an emphatic 7-3 win at the Bernabeu.

Some Los Blancos supporters had already responded to the Blatter jibe themselves by brandishing banners asking: "Respect?."

Ronaldo then went one better when he lashed home an inch-perfect penalty before, in tandem with Marcelo, whipping out the salute celebration to mirror Blatter's impression. 

Take a look at a video of the saga below:

Talk about an emphatic response to the unlikeliest and pettiest of critics.

Just in case that scathing acknowledgement wasn't suffice, though, Ronaldo went onto win the Ballon d'Or that year and propel Real Madrid to La Decima. Not bag going, huh?
