A look at what happened when Jurgen Klopp tried to buy a player from Tottenham.
Tottenham chairman Daniel Levy has been a master of negotiations when it comes to player sales in recent years.
Getting £86 million for Gareth Bale was one thing, but managing to net £10 million for Paulinho, and £3 million for Younes Kaboul this summer was just as noteworthy considering their status as deadwood in the Spurs squad.
His efforts to convince teams into sales at Tottenham's demands do not always work, see reference a failed negotiation with this weekend's opponent Jurgen Klopp three transfer window's ago.
German newspaper BILD reported how Dortmund attempted to sign Lewis Holtby from Spurs in January 2014, when suffering an injury crisis in midfield, with sporting director Michael Zorc making an approach to the North London club.
Tottenham responded telling them they wanted £4.6 million for Holtby, and as BILD reported, Dortmund and Klopp decided the price was too steep.
For Spurs the demands temporarily backfired, having to loan Holtby to Fulham in the same transfer window.
Yet Levy got there in the end, selling the German this summer to Bundesliga side Hamburg for £4.6 million, as reported The Guardian, a profit on the £1 million Tottenham paid to sign him from Schalke.
Klopp and Dortmund stuck to their guns, but Holtby is a quality player who could have flourished under his management, and the deal was an opportunity missed for all - except Hamburg.
It is just fortunate for the Liverpool boss that Spurs did decide to sell him after all, and the midfielder is not part of a Tottenham team which could inflict an opening defeat in his first Premier League game, and cause him to consider how he could have changed it.
Liverpool can take from this that they have a manager who sticks to his guns, and will not panic buy when the situation demands it, or pay over what he sees as a player's market value.
