Liverpool defender Mamadou Sakho is on his way back from injury.
Sakho has missed Liverpool's last 10 games because of a thigh strain and says he can provide the authority they need at the back.
"For me it comes naturally," he said. "There are different kinds of leaders technical leaders, dressing room leaders, psychological leaders.
"I'd rather keep my personal objectives to myself so people don't think I'm too pretentious. But I am a very ambitious person. I have set personal objectives. The team has set some too and they are quite similar."
