Liverpool boss Jurgen Klopp was full of praise for Rafael Camacho after his side's 4-3 win against Crystal Palace on Saturday.
The Reds overcame going behind to seal a big win in a well contested game.
And young defender Camacho had to make a crucial tackle late in the game to ensure the Reds avoided conceding an equalizer.
"I told him immediately after the game that he'd already made the most important challenge of his life," Klopp said to the club's official website.
"I'm not sure he really got it – he looked at me like 'What is he talking about?' – but it was really massive.
"He's good in defensive challenges. He's an offensive player in his mindset and everything but look at our full-backs and where are they most of the time? You need these offensive skills.
"On the other side there will be moments when you are alone on the pitch against a world-class player and they are looking to nutmeg you or whatever.
"It is the learning process Robbo went through. He was a fantastic left-winger but played full-back and now he is a full-back. That's really cool.
"I was really happy in that moment but I have seen similar situations from him [Camacho] before."
