The Reds boss was relieved to see his side fight back from a spot-kick he is adamant should not have been awarded
Liverpool manager Jurgen Klopp described the decision to award Sheffield United a penalty on Saturday as an "injustice" as the Reds came from behind to claim a 2-1 win.
After just 11 minutes at Anfield, Fabinho was ruled to have fouled Oli McBurnie on the edge of the box with Sander Berge making no mistake from the spot to give the Blades an early lead.
Despite the early setback, the Reds fought back and pulled level just before half-time as Roberto Firmino scored his first goal of the season from close range.
