Brendan Rodgers says Liverpool and England captain Steven Gerrard is still looking for ways to improve his game.
The 32-year-old is poised to reach another notable landmark on Sunday, with it expected that he will line-up against Newcastle United and make his 600th Liverpool appearance.
Gerrard has been a model of consistency throughout his distinguished career, but he is not one to rest on his laurels and consider himself to be the finished article.
Rodgers told the Reds' official website: "He's been brilliant since I came in. He's 32 years of age, captain of the England team and he and I are still looking at ways to improve his game - and that is a big mark of respect to him because he's achieved many things in the game.
"We're looking at videos, analysing his game one to one and looking at areas he can improve - I think that says everything about him, about his mentality and his willingness to want to improve.
"I've said it before and I'll say it again, he's an iconic figure for this football club and hopefully on Sunday he gains that 600th appearance.
"He, along with the likes of Jamie Carragher, are the great stalwarts of this club.
"I think he's still got a lot left in the tank because of his motivation. Mentally he wants to achieve and physically he's looking very good at the moment."
Rodgers, Gerrard and Liverpool will be hoping a meeting with Newcastle allows them to improve on a home record which has made for dismal reading of late.
Rodgers added: "I think there have only been three victories over the course of the year.
"It's something we want to improve. We tend not to want to look back so much and try and look forward.
"We've had difficult games this season at home and been unfortunate not to have won more of those in the league.
"As of late, that performance level has picked up and we've looked solid from behind. Our game in terms of our passing and moving has been very good. We just need to continue with that."
