However, he also believes Xabi feels he has still much to achieve with champions Bayer Leverkusen.
Kuyt, now coach of Beerschot, told Ladbrokes 1-2-Free: "I didn't speak with Xabi about the Liverpool job earlier this year, so I don't know exactly what his thoughts on it were. But when a club like Liverpool is coming for you, as a manager, and you have history there as a former player... you have to be a real man to turn a club like Liverpool down.
"But I think he did it with good reason. He is in the middle of making an unbelievable career, and what he achieved last season with Bayern Leverkusen was amazing. And I think he had a feeling that he was not finished with that job yet.
"I think he wants to become an even better manager, get some more experience and, I don't know, maybe it's a job he'll look at again at a later date. I don't think for a second that it's a case of him not being interested in Liverpool."
