The England winger had been told by Rodgers late last year that he would be allowed to leave the club.
"My response had to be to play well," he told the Sunday Times.
"As my dad said, 'Prove to him, give him food for thought'. I don't know if it was a gee-up or what, he [Rodgers] certainly tests players - it was good, I appreciated the straightness, most players do.
"I wasn't playing, he was bringing in new players in my position and there was no point, at my age, beating round the bush.
"Since that conversation I've almost played every game, 11 out of 12. Nothing's been said. I don't know what the plan is but right at the moment I'm doing all right and in the team.
"He stressed I have to play high up the pitch and get into positions when I can create and score. That's my focus every game now, do well and make it hard for him to leave me out. I'm in control of the shirt at the minute, others have to get it."
