For the Reds, it was a win reminiscent of their at-all-costs run to the title during Liverpool vs Fulham 1-0 on Wednesday – not the prettiest, but three more points.
For their fourth in a run of five games in 15 days, a reshuffled Liverpool took to the field against Fulham, with Darwin Nunez, Luis Diaz and Mohamed Salah starting together for the first time since October.
There were problems early on with one player coming in, with Kostas Tsimikas switching off completely to allow Harry Wilson through for a cross-shot only denied by Virgil van Dijk.
Trent Alexander-Arnold was the Reds' biggest threat in the opening stages, with his third shot in the first 10 minutes trickling just wide.
Bernd Leno was quick off his line to thwart hopeful balls over the top and passes threaded by the right-back in midfield, while Alisson was required to keep an improving Fulham at bay.
Liverpool got their opening through another penalty, with Nunez grazed by Issa Diop, allowing Salah to step up and make it back-to-back spot-kicks and 1-0.
The Reds looked confident coming out for the second half of Liverpool vs Fulham, zipping the ball around sharply, with Jordan Henderson laying Nunez on for a half-chance skewed wide.
Still, Fulham were able to probe through the creativity of Wilson and Willian and the running threat of Carlos Vinicius, though Van Dijk and Ibrahima Konate dealt with the striker well.
As the hour mark passed, Jurgen Klopp turned to his bench, with the expected change of Diaz out, Cody Gakpo in as the Colombian continues his cautious reintegration.
A combination between Willian and Vinicius carved out a close-range chance for the latter, but their Brazilian countryman, Alisson, was on hand with a brilliant save.
There was to be no second goal, though, with Liverpool instead standing firm and carving out their five consecutive Premier League victory.
