Jurgen Klopp snapped up the highly-rated young centre-back last month for a fee of £1.3 million, and his experience at first-team level could help smooth his pathway into Liverpool's squad for the next season.
Nathaniel Clyne opened the scoring for the Reds in the sixth minute of the match before Rhian Brewster - who was part of the 2017 Federation Internationale de Football Association U-17 World Cup-winning England team - scored a brace late in the first half to make the scoreboard read 3-0.
The Guardian wrote how the backroom staff at Liverpool had been impressed with Origi's attitude on the training field and this played a big part in the decision to open talks over his new deal. "I think the next years are going to be very special - prime years, maybe - and I'm going to try to use them to the fullest", said Origi.More news: Alegria advance to AFCON semis after beating Cote d'Ivoire on penalties

"Rhian Brewster I love the boy, he is fantastic player but one of the goals I would have scored". Why should I play it down? "It depends on him and we'll see", the German added.
Rhian Brewster; Oxlade-Chamberlain didn't play a year ago; all the young boys today.
There is also a place for 19-year-old Rhian Brewster, whom Klopp is keen to integrate into the first-team set up for the coming season. We will see what we do, but I don't think it will be the biggest transfer window of all time. "There will be opportunities for him, I'm really sure".More news: The Final Fantasy 7 remake may not be PS4-exclusive at launch
