Liverpool boss Jurgen Klopp has explained holding back Andrew Robertson.
The Scot has battled for minutes since his August arrival from Hull City.
Klopp insists Robertson can learn a lot from Moreno's attitude to improving and follow in his footsteps.
“That's the exact situation for Andy Robertson. People will say: 'Why do you do that [sign Robertson], because he is here and not playing?'
“Because he has to learn, but there is no problem. We are in conversation, talk about it and he has to improve."
Meanwhile, Liverpool striker Sadio Mane admits he's struggled to handle the pressure of delivering for Senegal.
Mane helped Senegal reach the World Cup with victory over South Africa yesterday.
The 25-year-old admitted after the game that having the spotlight on him with so much at stake almost proved too much.
“It was not easy but I had to keep pushing. It wasn't easy for me, there was too much pressure on me but that has become normal," Mane said.
He added: “It was important to be able make a difference.
