Harvey Elliott marked his return from injury with his first Liverpool goal as Jurgen Klopp's side beat Cardiff 3-1 at Anfield to set up a FA Cup fifth-round tie against Norwich
Elliott, who had not featured at all since dislocating his ankle during a Premier League meeting with Leeds in September, controlled an Andrew Robertson cross and fired a clinical finish into the corner (76) after coming off the bench in the second half
Elliott later described the goal as a moment he will "cherish forever" while Klopp added: "He was patient coming back and he's still a fearless boy and a great footballer
 Getting this goal was a really touching moment
"Earlier, Diogo Jota had put the hosts in front with a superb header from Trent Alexander-Arnold's free-kick (53), before Takumi Minamino doubled Liverpool's advantage from a cut-back by new signing Luis Diaz (68), the substitute marking his debut with an assist
Cardiff did give their fans something to cheer after that, with teenage substitute Rubin Colwill firing past Liverpool goalkeeper Caoimhin Kelleher after exchanging passes with Isaak Davies (80), but the Championship side were well beaten in the end as Liverpool advanced to the fifth round for only the second time under Klopp
It might have been a different story had the visitors been able to build on a resilient first-half performance during which they frustrated a Liverpool side still missing Sadio Mane and Mohamed Salah at the Africa Cup of Nations
Jota would eventually take his tally for the season to 15 goals, but he missed a gilt-edged chance inside the first few minutes when he shot too close to Cardiff goalkeeper Dillon Phillips after creating space for himself with a brilliant turn
It set the tone for a wasteful first-half showing, with Curtis Jones, Roberto Firmino and Naby Keita also spurning opportunities as Liverpool reached the halfway point having had 10 shots but only one on target
Cardiff saw little of the ball but did threaten on occasion, not least when Mark Harris saw a penalty appeal turned down - the decision upheld by VAR - after going to ground under pressure from Ibrahima Konate in the Liverpool box
The VAR was called into action again moments after the break when Kelleher, starting in place of Alisson Becker, raced off his line in an attempt to make a clearance but ended up bringing down Harris
The young goalkeeper appeared to have his studs up as he challenged Harris but a yellow card was deemed sufficient
Jota's outstanding opener, when he directed Alexander-Arnold's delivery into the far corner from 12 yards out, arrived soon afterwards
The Portuguese international then volleyed narrowly wide from a corner but Liverpool didn't have to wait long for their second goal when Diaz, whose introduction was met with raucous cheers by the home fans, won possession off a dawdling Perry Ng to set up the onrushing Minamino
There was subsequently a worrying moment for the Colombian international, a January arrival from Porto, when he went down in pain and needed treatment following a coming together with a Cardiff player, but while the collision left him with a cut on his knee, he was able to continue
Elliott's strike completed a satisfying afternoon's work for Liverpool, for whom Kostas Tsimikas was particularly impressive at left-back, although the travelling Cardiff fans also experienced a moment to savour when 19-year-old Welsh international Colwill fired home their consolation goal
Goalscorer  expressed his delight afterwards, telling : "It's hard to put into words at the moment
 It's what I've been put into the team to do - to score and assist
 Thankfully, it's come today in front of the fans after a long time out
"It's my job, and I just have to keep doing it
 It's a moment that for myself and for my family we will cherish forever
"On his goal, he added: "It wasn't too bad
 Watching Diogo next to me, I've been getting tips off him!"Th 18-year-old also paid tribute to Liverpool physio Joe Lewis for helping him through his injury rehabilitation
"One man I have to thank is Joe," he said
 "He's one of the physios who took me in during the early hours of the morning and we didn't finish until late at night
 He made me strong again
"A big shout out to all of my friends and family as well, especially my mum and dad
 They've supported me throughout
 A massive thanks to the fans who gave me all the love
 The injury is behind me now and I'm back
"Asked about Harvey Elliott afterwards,  told : "He was unlucky with the injury but then lucky with the whole process afterwards
"Everything has gone well
 He did an incredible job and the medical department did an incredible job
"He was patient coming back and he's still a fearless boy and a great footballer
 There are not a lot of good things when you get an injury like that, but when you are that young, you deal with it better
"Getting this goal was a really touching moment
"Luis Diaz, meanwhile, enjoyed a promising debut from the bench as he set up Liverpool's second goal but he also needed treatment after a Cardiff boot landed on his knee in the closing stages
Klopp added: "Luis came on and it's just a little bruise, a little cut
 Everyone in the dressing room said, 'Welcome to England'
 That will be a scar in the end from his first game, but it's all good
"The ties will be played in the week commencing Monday February 28, 2022
