It wasn’t
Torres leaves January 2011. In that transfer window, Liverpool bought both Suarez and Carroll. Carroll leaves Liverpool in 2013 (after going on loan the previous season), a year prior to Suarez
Suarez’s replacement was Balotelli, equally hilarious
That summer was a farce. A struggle between Brendan Rodgers vs LFC transfer committee and poor replacement planning
Apparently, LFC main player to replace Suarez was Diego Costa. They targeted him for 2 years but he decided to join Chelsea instead. Then LFC tried to get as plan B Alexis Sanchez from Barcelona but he decided to join Arsenal. Then Rodgers asked for Benteke as plan C but Aston Villa refused to sell him at any cost. So LFC as band aid and last resort went for Balotelli because why not?...
People forget how undesirable it was to join them prior to Klopp joining. (Still a struggle with some example like Caicedo, Lavia and Zubimendu but even then it's not as it used to be)
