Caoimhin Kelleher is one of four former Liverpool players now plying their trade at Gtech Community Stadium, along with Jordan Henderson, Fabio Carvalho and Sepp van den Berg.
The goalkeeper has started all eight of the Bees’ league matches since completing his summer transfer.
Asked about Kelleher, Slot said: “He felt it was time for him to start playing – and he has shown that he is right because he is doing really well.
“And although I haven’t worked with him, we are also going to face Jordan Henderson.
“In Holland they cannot stop talking about how much Ajax is missing Jordan Henderson, so that tells you how important he was for Ajax and how important he has been for Liverpool and how important he now is for Brentford.”
