Rodgers is delighted with the Welshman's first weeks at Anfield.
He told liverpoolfc.com: "Joe has been a revelation in these first few games and I'm sure that will improve and get better because he's 22 years of age, he's got an appetite and a desire to improve his game and I think over the course of the next coming years Liverpool will get the chance to see that.
"The biggest compliment, I think, everyone that has seen him play is that he looks like a Liverpool player. Liverpool supporters are educated, they really understand good footballers, people who can pass the ball and take pride with the football.
"He has been very good, and I think there's a lot more to come from Joe as well. A young player that came with a big price tag but I know Joe very well and I knew it wouldn't affect him."
