Liverpool will play A-League side Sydney FC at the ANZ Stadium on May 24 and Klopp has added a quartet of former players to his current squad for the game.
Gerrard became a youth academy coach at Liverpool in January, after ending his playing career with LA Galaxy.
The German manager has also 'called up' former defender Jamie Carragher and ex-Anfield winger Steve McManaman, both now television pundits, along with Danish former defender Daniel Agger.
"I thought we have to show the whole Liverpool package - that means the actual squad and a few of our legends," said Klopp.
"They are still young enough and look good enough in the kit that we can show them. So, use the opportunity that we still have. It's good for the players and I think the supporters will enjoy it."
