Sterling has decided to commit himself to the Reds for the next five years.
"What I'm seeing is that this is a kid who's had the right attitude drilled into him, and I think that's a good thing for Liverpool - a big thing," Fowler told the Mirror.
"Sterling has a great talent, but what he also has that makes him stand out is a maturity in his approach to the team's needs that you rarely see in youngsters. That shows he'd being coached and developed in the right way.
"It's so easy these days for kids to believe their own publicity. They are treated like superstars, they get massive money even before they've done anything, and they don't have to clean boots or the terraces any more!
"But I watch Raheem and I can see he has respect for the team and for the senior players around him.
"And his decision-making is good - he doesn't just want to beat players and then shoot to get personal glory.
"I think the manager has to take some credit in that development. He's still a kid and got a long way to go - he needs to improve his final ball - but Brendan Rodgers has already proved himself as a coach at the top level, and he's in the right hands."
