However, Klopp wants the player to start developing his all-round game.

"I love the boy, he is fantastic player, but one of the goals I would have scored," said Klopp.

"We knew Rhian was a good player before. Why should I play it down? I just don't want to talk after a game about the guy who scored two goals.

"I saw a really good game and Rhian is a fantastic player.

"One hundred per cent [it is a big season] but it depends on him as well. Divock Origi stays which is good news, Bobby Firmino is still there.

"Rhian Brewster is a top striker, he is a top talent and I have told him already that he has an important role this year but how important depends on him.

"We will see. He has to play different positions as well – the centre, wing is possible I think, we will see how we line up, but there will be opportunities for him. I am sure."

Liverpool have so far signed youngster Sepp Van Den Berg but are not expected to make any major signings this summer.

"Rhian Brewster, (Alex) Oxlade-Chamberlain didn't play last year, all the young boys didn't play for us last year," said Klopp.

"The transfer market is open. We will see what we do, but I don't think it will be the biggest transfer window of all time."

In addition to Brewster's double there were also goals for Origi, Curtis Jones, Bobby Duncan and Nathaniel Clyne in a squad which relied heavily on youth, with a number of internationals still to return to training.

Of the squad which won the Champions League 40 days ago, James Milner, Adam Lallana, Simon Mignolet, Joe Gomez, Oxlade-Chamberlain, Fabinho, Origi and Joel Matip all featured for 45 minutes at Prenton Park.
