Rodgers says Soyuncu is exactly what Leicester needed to fill the boots of Harry Maguire.
He said: "When you work closely with him, you see his quality. He had big boots to fill and he's been very, very good in both games.
"For a modern-day centre-back, he's exactly what you want."
And Rodgers expects Maddison to be called up to the England squad.
He said: "He's got such a brilliant football brain. Technically he's at a very high level. He finds space and can manipulate the ball and create chances for other players.
"He's very much a team player and he's a real joy to work with."
