The 23-year-old struggled for form after moving to Anfield but has now established himself as a regular and believes he has kicked on under the former Swansea boss
The 23-year-old joined Liverpool from Sunderland in 2011 for a fee reported to be in the region of £20 million and struggled to justify the hefty price tag in his first season at the club.
But the England international, who cemented a place in Rodgers' starting XI in the second half of last season, has played every minute of Liverpool's winning start to this campaign.
And Henderson admits he is pleased with his development under the former Swansea boss.
"I feel as though I've progressed over the last year or two," he told the club's official website.
"I'll try and push on. The manager has been brilliant with me and everybody else here. He's been fantastic on a personal level.
"I think I've improved my game since he's come to the club and he's helped me to do that.
"We worked very hard pre-season and then in the games we have looked pretty solid as a team. The manager has definitely been working on that during the pre-season. Last three home games, we've done really well."
