The Turkey international scored three goals in 12 appearances for the Reds after joining on a season-long loan from Real Madrid in August.
But Sahin’s Liverpool deal was terminated in January, with the 24-year-old joining his former club Borussia Dortmund on loan until the end of the season.
Despite admitting it was an honour to play for the five-time European champions, Sahin says he was frustrated by Rodgers’ decision to play him behind a striker – and not in his preferred holding role.
“Brendan Rodgers wanted me to play as a 10 but I do not play behind the forwards,” Sahin told Spanish newspaper AS.
“I spoke with him and asked him why I was playing there. It is not my real position. The boss could not answer me… still, I am not sorry about it.
“To play in the red jersey and be in Anfield is something marvellous.
“Maybe if I had not gone there I would not have been able to return to Borussia Dortmund. For that, I am happy.
“But I have left Brendan Rodgers, thanks be to God.”
