The Reds boss praises the Turkish midfielder's start for the club following his loan move from Real Madrid but hints that his price and availability will determine his future
The 24-year-old has started his season-long spell at Anfield in encouraging fashion, scoring three goals as the Reds posted victories over West Brom in the League Cup and Norwich City in the Premier League.
However, the Northern Irishman acknowledged that the player's price and availability - should Jose Mourinho desire his return - will play a huge role in any possible deal.
"I don't look beyond the loan period because there are lots of things which will determine whether [Sahin] ever came here [permanently]," Rodgers told reporters.

"One has to be availability. Jose may decide after one year playing he is really the type of player he wants around his squad.
"Two: He might not be affordable. Affordability is important as well. We'd all love Lionel Messi but whether you can afford him or he's available is another thing."
Rodgers also stated that, while the eventual decision may be out of his hands, the loan move can still be of great benefit to both club and player.
"All I can concentrate on is Sahin coming in here and helping him become the best player he can possibly be," he added.
"If he finds he enjoys it here and he fits into the way we work, which I am sure he would do because he is a good guy and understands the game tactically and is prepared to fight for the club, then that is something come the end of the season we will talk about.
"But at this stage it is way too early. He is just starting to get up to speed fitness-wise but what he is is a real good guy and you have seen his performances."
