Rodgers signed the Belgian goalkeeper from Sunderland over the summer.
"I'd seen him over the last few years, he's adapted to the Premier League. He is a brilliant shot-stopper," Rodgers told the Sunday Telegraph. "John Achterberg, our Dutch goalkeeping coach, has been monitoring him for years.
"You see his presence, he is good with his feet, that is important, it is one of the big things I look for in my goalkeeper - the way he deals with the ball so when we have the ball we have 11 players not 10 outfield players and a goalkeeper. So he's comfortable with the ball at his feet, he makes saves and again I go back, he had the hunger to succeed. He was going to come from a really good club in Sunderland and prove he could be the number one goalkeeper here."
