Cape Town - Liverpool manager Jurgen Klopp says Sadio Mane's goal-scoring return to action came at just the right time as the Reds prepare for Atletico Madrid.
Senegal attacker Mane climbed off the bench to prod home the only goal of the game and seal Liverpool's 17th straight Premier League win in a scrappy affair at Carrow Road.
The wind and rain of Storm Dennis spoiled any chance of attractive football, and the Reds rode their luck en route to yet another league win.
Boss Klopp's men are now just one win away from matching Manchester City's Premier League record run of 18 consecutive victories.
The Reds will now make the trip to Atletico Madrid for Tuesday's Champions League last 16 first-leg clash, with Klopp tipping Mane to be ready to star again in Spain.
"It helps when you have such quality on the bench to bring on," said Klopp. "Yes Sadio could have started today of course but I want to have a free decision for Tuesday.
"You don't think they should play two games in such quick succession. The quality of the others is just too big that you have to push somebody through. It was perfect for Sadio to have a few minutes but it looked like he was ready, yes."
Liverpool flailed for fluency in a challenging first half as the conditions ruined the Carrow Road encounter.
Mane removed any frustrations though by plucking Henderson's lofted pass out of the air with a fine first touch, before poking past Tim Krul to kill the Canaries' stubborn resistance.
Mane had hobbled out of Liverpool's 2-1 win at Wolves on January 23, but was quickly back to his best in Norfolk on a stormy Saturday night.
Mere formalities remain before Liverpool seal their first top-flight title since 1990, but manager Klopp admitted his side had struggled against the elements in Norwich.
