Gerrard will miss the visit to Tottenham on Sunday with a hamstring injury but Mignolet is confident the Reds have enough in them to cope.
He said: "We have other leaders in the team as well.
"We have a decent enough squad to deal with injuries, to cope with those kind of things.
"I am sure someone else will be ready in the dressing room if the gaffer asks him to play.
"Every game we go into hopeful of getting three points. We will go to Tottenham and be positive."
