Liverpool boss Jurgen Klopp paid tribute to Loris Karius after victory over Brighton.
Karius has left Liverpool for a two-season loan with Besiktas.
Klopp said: "We said goodbye yesterday. He is really looking forward to it, so that's good. It's good for him, I really think. Loris is a fantastic goalkeeper at a very good goalkeeper age. A lot of people speak now about our improved defensive things and as good as Alisson was in the last three games, in most of the games when we were already really good in that he was not here.
"It was Loris in goal and he did a lot of good things. When I saw the Besiktas team, it's quite an experienced team they have there. They have a good chance to win the league in Turkey, that's cool. Now they have a really good goalkeeper.
"I'm really happy for him and he was very happy about the opportunity as well. All good. And we have Simon Mignolet here, a wonderful, perfect goalkeeper as well for us. That's the situation now. Plus, the two kids [Kamil Grabara and Caoimhin Kelleher] of course."
