The Uruguayan, in blistering form for both club and country this season, has never been shy to reveal his emotions on the football pitch - be it after scoring yet another wondergoal or expressing his frustration at a missed chance.
But the 27-year-old says he is completely different off the field of play. Aside from the "odd crossword" with his wife, he claims, Suarez is a "very calm person."
That's why, amidst the barrage of 40-yard strikes and endless nutmegs he might see, Suarez is often uncomfortable watching highlights of himself back on television.
"On the pitch, I argue, I shout, I talk rubbish and generally do anything I can to get ahead. I’m totally different," he told FourFourTwo.
"I forget about everything else, sometimes I’m a bit embarrassed by all the shouting when I see it back.
"Away from the pitch, I’m a very calm person. I maybe have the odd crossword with my wife, like any relationship, but that’s it.
"Nobody in England knows the real Luis Suarez."
The Reds striker, though, says he is slowly adapting to "the English way." Unlike when he first arrived at Anfield, Suarez admits he now tries to stay on his feet more after being challenged.
"Everybody has their way of behaving on the pitch. I now try and stay on my feet more than in the past because I’m learning the English way.
"Before I’d feel a touch and go down more, so I think I’ve matured again in that respect."
How much is Suarez worth to Liverpool right now?
