The German has spent the season on loan at Besiktas after losing his place to new signing Alisson last summer.
Karius endured a night to forget in last season's Champions League final defeat to Real Madrid. But Liverpool have the opportunity to redeem themselves this weekend.
The Merseyside outfit reached the final in stunning circumstances, fighting back against Barca to win the second leg 4-0.
And despite watching from afar, Liverpool goalkeeper coach John Achterberg has revealed that Karius was as pleased as any of his Reds team-mates.
The revelation comes amid news that:
“Loris texted Jurgen and myself when we reached the final,” Achterberg told The Times.
“He said he was happy for us and hopes we now win.
“I think that says a lot about him.”
“He is a good guy,” he added.
“He is not a bad goalkeeper, but the situation was not easy for him.
“It was the best solution for him to go and play, rebuild his confidence, and then enjoy his football again.”
