Sissoko has picked up three yellow cards in four Premiership appearances this season but Rafael Benitez has defended his midfielder and says the Mali international's reputation is earning him unfair bookings from referees.
"It is easy to show a yellow card to a young player who is not a big name," said the Liverpool boss.
"You watch other games and see big names who do not get yellow cards at all and their tackles are maybe even worse.
"He just needs more experience. Sunday was a big game and people were talking about him.
"But he has a high work-rate and never goes into a tackle with a bad intention. Other players do much worse and receive nothing."
