Gerrard, Sterling, Lucas and Mignolet all feature.
The Reds are trying to kick-start their season after a poor start, and backed up their late win over Stoke City at Anfield on Saturday with a victory that was a little more impressive in the East Midlands.
After they fell behind to a Simon Mignolet own goal, the Reds hit back from goals through Adam Lallana, Steven Gerrard and Jordan Henderson, as they overcame a side that was reduced to 10 men in the second half, with their captain Wes Morgan dismissed.
The result moves the Reds into the top half of the table, but what did we learn from their performance?
Here are five things:
Decision to rest Gerrard was vindicated
Steven Gerrard had his best game of the season in the advanced 'number 10' role. He looked creative, lively, fresh and scored a goal that has been typical of him winning Liverpool matches throughout his career. After a few eyebrows were raised at the weekend over Brendan Rodgers resting him, it was a performance that didn't make Gerrard look 34.
Different members of the side starting to find goals
There has been a lot of talk this season from players that different areas of the side need to chip in with goals given the sale of Luis Suarez to Barcelona, and the loss of Daniel Sturridge to injury. After Glen Johnson's late winner at the weekend, those that perhaps aren't regarded as prolific goalscorers in Adam Lallana and Jordan Henderson found the net. It's something that needs to happen on a more consistent basis and help take the pressure off the forwards.
Lucas Leiva is still an integral part of the squad
For the third game in a row, the Brazilian featured in the midfield and this was his best performance of the three. He was competitive in the middle of the park, broke up and read the play well, as well as taking a lot of the strain on the defence behind him. It makes it all the more remarkable that the club were willing to listen to offers for him in the summer.
Fresh question marks over Simon Mignolet
After a decent performance at the weekend against Stoke City, Mignolet had another display to forget. He should have been punished for his careless pass out of the area that presented an opportunity to Esteban Cambiasso to stroke home, only for the veteran midfielder to miss the target. The Belgian's misery was compounded with an own goal, even if it was unfortunate. But despite the positives from last night's game for the Reds, for the time being at least, Mignolet seems to be a negative.
Still huge pressure on Raheem Sterling to perform
Within a couple of minutes of last night's game kicking off, Sterling was seemingly limping around, and didn't quite look 100%. One can't help but feel if this was any other teenager, then he will have been substituted earlier than into second half stoppage time. He still played his part in causing mayhem in the Leicester defence, though.
