Suarez goes into the Reds' game with Sunderland on Wednesday fresh from a hat-trick against Cardiff City, and Rodgers was quick to insist that the 27-year-old has displayed a strong character on and off the pitch this season.
He told The Mirror: "I think it's been nice for people to see the other side of Luis this season. People don't see he's a real quiet, humble guy off the field who becomes a gladiator when he crosses the white line.
"This year, he has been a model of brilliance. On the pitch it's never been questioned and if anything he has improved on that level.
"He's up for every game. He's a real strong pillar of our team. He's really dominant, that's why I had no hesitancy at the time making him skipper."
Liverpool could close to within a point of Chelsea at the top of the Premier League table if they beat the Wearsiders.
