Liverpool beat Manchester City 2-1 at Anfield on Sunday and Brendan Rodgers praised "sensational" Philippe Coutinho, saying there is a lot more to come from the 22-year-old.
Coutinho was the man-of-the-match winner in their 2-1 win over Man City and the attacking midfielder scored a wonderful winning goal to cap his performance on the day.
Jordan Henderson broke the deadlock in the 11th minute but City responded through Edin Dzeko and the moment of Countiho magic came when he scored a sublime goal in the 75th minute.
However, the Liverpool manager hailed the Brazil midfielder's impact in the game.
"To beat Joe Hart, who I rate extremely highly, at 6ft 5 and a top-class goalkeeper, to beat him from that angle with that power was a phenomenal strike - as was Jordan's,” Rodgers said.
"In particular since he signed his contract, he has started to score goals. He's a joy to watch. He's a kid that has got so much ahead of him in the game at 22 years of age.
"People forget he came to us at 20, still developing and adapting to a new country. He's a sensational footballer and now he's starting to add the goals to mirror that quality," he continued.
"I think he is a star in the Premier League already, but there are still improvements he can make," Rodgers continued in his assessment at the post-match press conference.
"He is a young player that has developed, he's got the trust of his teammates, he is playing at a football club that adores him and he loves it here, hence him signing a new deal.
"He is playing for a team that wants to play a technical game and you add all of that to his humility as a kid to want to improve - he's a boy that wants to train every day, wants to do extra work.
"He is an absolute pleasure and a joy to work with. He's a kid we brought in a couple of years ago, and it'd be frightening to know what he'd [now] be worth in the market, but there are still improvements to make."
