The current Reds boss and the iconic former club captain narrowly failed to cross paths at Anfield in 2015, with Klopp appointed in the October after Gerrard had moved to Los Angeles Galaxy during the summer.
They did link up professionally later, however, as Gerrard began his coaching career with the Academy, taking charge of the U18s squad for the 2017-18 campaign before becoming Glasgow Rangers manager.
A post-season friendly in Australia in May 2017 had also provided a brief chance for Klopp to work with Gerrard as a player – a tantalising scenario he wishes would have happened for real.
