Rodgers insisted: "The reaction to Hamza was right over the top for me. The boy went in to make a tackle.
"Mo Salah is a world-class player but you can tackle him. It wasn't even a bad tackle.
"You have to ensure they stay aggressive because that is their game, without overstepping the line.
"If you look at the team we play in an aggressive but sporting way.
"Young Hamza is one of those lads that play on the limit and is fighting for his career.
"His strength is recovering the ball and retrieving the ball, which he is very good at, and he is learning other aspects of his game.
"The only way is constant work and talking with him."
