Liverpool manager Jurgen Klopp has admitted that he is a fan of Christian Pulisic and has refused to rule out a future move for the Borussia Dortmund winger.

The America international, who spent time working with Klopp as a youngster at Dortmund, has been strongly linked with the Reds, Tottenham Hotspur and Manchester United over the past year.

Pulisic's father recently dismissed the press reports, though, and Klopp respects the fact that the 19-year-old - reportedly valued at around £50m - is currently tied down by Dortmund.

"He has a contract at Dortmund, no? That's the first problem," he told reporters ahead of Liverpool's friendly against BVB on Sunday evening. "I like Christian, I've known him since he was a kid. He's still not really old, he's a fantastic player, and it's deserved people think highly of him in America.

"In Germany, it's the same. If he wants to play in England or whatever one day then for sure he has the chance to do so but he's at a really good club for his development at this moment. It's really good to be at a club where they know him already.

"He had not his best season last year but he was still a decisive player but it's important in that age group that there's no rush. He still has 14 or 15 years to play in his career and that's good and he wants to be the best Pulisic he can be. For this, there is still space for development.

"If - at one point - he will join us, I don't know. I like him, it's not that that could be the problem, but we respect contracts still and there's no market I know about at the moment. We did our business and Dortmund are doing theirs. All good."

Pulisic, comfortable on either flank, scored four goals and set up five more in the Bundesliga last season.
