Chelsea trailed at Anfield from the 58th minute when Daniel Sturridge acrobatically fired beyond Willy Caballero, but Emerson Palmieri bundled in a controversial equaliser before Hazard beat five Liverpool defenders in the course of a dazzling move and smashed the victor past Simon Mignolet.
Hazard stole the show at Anfield, where Chelsea overturned a 1-0 deficit to rally to a 2-1 win in the third round thanks to the Belgian attacker on Wednesday.
I am all for giving young kids a chance when the time is right, but Chelsea are likely to field a strong team and this is not the moment for Klopp to take too many risks and threaten the momentum the team has built up so far.
"You have two players that are clearly offside and they block my players".
"We won so in the league we will change some players, they will change some players but we want to win again".
In a formidable display of skill and speed, Eden Hazard slalomed past Liverpool players before scoring the goal that sealed Chelsea's progress in the League Cup. To be on the pitch again was really nice and I think I did my job the best I could.
"It would be great, I would love to do it and it's a trophy", he told Sky Sports.

Chelsea will have their resources tested this season by the Europa League, but the performance of their fringe players at Anfield suggests that Sarri's team can combine an assault on both domestic and European competitions.
"It is going to be a good day for us, I hope".
Against all odds, the Englishman shot off-balance and missed the target completely in what has to be one of the most shocking misses you will ever see.
"It's a big win but to be fair it was a close game". It's fair to say they are a brilliant team.
