The 26-year-old joined Liverpool from German side Mainz 05 in the summer of 2016 but he failed to impress when given the chance in goal and was shipped out on a two-year loan deal to Besiktas in Turkey last year.
Karius reserved arguably his worst performance in a Liverpool shirt for the 2018 UEFA Champions League final in Kiev when he was at fault for two of Real Madrid’s three goals.
Liverpool have since brought in Brazilian goalkeeper Alisson Becker, who recently won the FIFA Men’s Best Goalkeeper award, from AS Roma for big money while former West Ham goalkeeper Adrian has been recruited on a free transfer as his understudy.
Nevertheless, Karius remains optimistic of featuring for Liverpool again when his temporary spell in Turkey comes to a close with his contract at Anfield not expiring until the summer of 2021.
"I have a loan until the end of the season and then I will see, back to Liverpool or somewhere else in England or somewhere in Germany, you never know," Karius told UK newspapers, via The Guardian.
"Right now my focus is on playing games here every week and then we'll see.
"I've enjoyed my time here. Of course if you play in England you are a bit more in the spotlight, but it's a good club here, of course with some problems now and then. It was not always easy the last year and a bit since I'm here but overall the first season was quite good.
"The Premier League is the best league so it's interesting of course but also I am still under contract at Liverpool, so maybe I'll play for Liverpool again, you never know.
"It's difficult to say now. If it's not Liverpool it will be another decent team I am sure, so I am not worried."
