Klopp has strong links to Dortmund after managing the Bundesliga giants for seven years and although he is an admirer of Pulisic, who's scored 12 goals in 97 appearances for BVB, a move this summer will not be happening despite fresh rumours.
Klopp, speaking ahead of his side's pre-season friendly with Dortmund on Sunday, said as quoted by the Mirror: "He has a contract at Dortmund. That's the first problem.
"I know Christian, I liked him since he was a kid. He’s a fantastic player, it’s deserved people think highly of him, in Germany it’s the same. If he wants to play in England he has the chance to do so but he’s at a really good club already.
"He had not his best season last year but he was a decisive player but it’s important, there’s no rush, that’s good and he wants to be the best Pulisic he can be. If he joined us, I don’t know, I like him, but we respect contracts and there’s no market I know about him.
"We did our business and Dortmund did theirs."
Pulisic is still only 19 and is seen as one of football's brightest young prospects, and is already the United States' leading light in the men's national team, while Klopp has already splashed out over £170m on boosting his squad so far this summer.
