Loris Karius says Jurgen Klopp was keen to keep him at Liverpool this season before sanctioning his two-year loan move to Besiktas, according to the Sky Sports.
Karius said: "He [Klopp] told me he would like to have me in the squad because he wants to have the best quality players.
"But I spoke to him and asked him for my wish, it is important to me to play for Besiktas. I talked to him for a long time and he understood my situation.
"I think it was a good deal for everyone. He wished me well but he said he would have liked to keep me."
