The youngster is yet to sign a new contract at the club despite months of negotiations, with him recently revealing to the BBC that he had turned down a 100k-a-week offer.
Before then, manager Rodgers had confirmed to the BBC that talks over a new deal had been postponed until the summer, leading to intense speculation about his future, with a number of top clubs being linked with his signature.
Now, Redknapp has revealed how the Anfield manager is likely to be feeling amid the ongoing uncertainty.
“Brendan can’t come out and say what he feels,” said Redknapp.
“I’m sure he’s upset with the way it’s been handled and what’s going on [though]. He’s got to keep the player onside; he doesn’t want to fall out with the kid.”
On Sterling, the former QPR manager questions why the player would want to leave a club where his development has been so profound.
It was Rodgers that gave Sterling his debut and has since made him a key player at the club, despite his age. As far as Redknapp is concerned, he should sign a new contract with the Reds as soon as possible and keep on improving beyond that.
“I think he’s at a great club,” added Redknapp.
“His football has come on and he’s really took off. He’s [also] got a fantastic manager who’s helped him. 100k a week is a fantastic contract, sign it and keep on improving.”
