Besiktas manager Senol Gunes announced that Loris Karius has become a “bit stagnant” and has raised concerns over his long-term future.
The German goalkeeper joined Besiktas on a two-year loan deal from Liverpool last summer following his Champions League final blunders against Real Madrid last season in Kiev.
In light of this, Reds boss Jurgen Klopp signed Alisson Becker from AS Roma in a £67m deal which left Karius with no other alternative but to end his two-year stay at Anfield.
But the 25-year-old’s hopes of rebuilding his playing career over in Turkey have not gone the way he had hoped with just five clean sheets in 21 Super Lig games to his name.
This has proven to be a major handicap for Besiktas’ hopes of challenging for the Turkish league title as they have conceded 34 times compared to leaders Istanbul Basaksehir’s 12.
And Karius’ fortunes at Besiktas appear to be showing no signs of improvement after another blunder enabled Omer Ali Sahiner to score for Konyaspor on Sunday.
While Besiktas did eventually emerge with a 3-2 win anyway, Gunes was left worried over Karius’ struggles and admitted he would have dropped the Liverpool loanee for veteran keeper Tolga Zengin had he been registered in time for the senior team.
“He was at fault for the goals he conceded,” said Gunes, according to Liverpool Echo.
“Karius has gone a bit stagnant, something is wrong with his electricity, motivation, enthusiasm for the game.
“It has been like that since the beginning. He does not really feel a part of the team.
“It’s something we haven’t been able to work out and, of course, I am partly to blame for this.
“Something is wrong, [but] he has also been unlucky.
“[He] is talented but it hasn’t worked out and we have a problem. Let me put it this way, if I still had Tolga available I would play him.”
Besiktas president Fikret Orman had announced in November plans for the club to sign Karius on a permanent deal from Liverpool.
The Turkish side do have the option to make Karius’ stay a permanent one in June 2020.
