astronomic profits were made from Jude Bellingham, Jadon Sancho and Erling Haaland<\/a>. The trio departed for a combined \u20ac248m after becoming global superstars in black and yellow.<\/p>\nCurrent fan favourites Gregor Kobel and Nico Schlotterbeck moved to Signal Iduna Park in recent summers for small fees; they may well be considered major bargains in a few years\u2019 time.<\/p>\n
396 appearances. 164 goals. 123 assists. 11 years of impeccable loyalty and sheer brilliance on the pitch. Any fee to acquire such a legacy can be considered a bargain.<\/p>\n
But the \u20ac17.1m paid to bring boyhood \u2018Borusse\u2019 Marco Reus home in 2012 stands as one of the best value football transfers of the century.<\/p>\n

However, as value goes, Borussia Dortmund have perhaps had better deals.<\/p>\n
This article looks back at some of the club\u2019s very best.<\/p>\n
\u0141ukasz Piszczek – Free<\/h2>\n
In 2010, Dortmund completed the acquisition of 25-year-old Polish free agent \u0141ukasz Piszczek from Hertha Berlin.<\/p>\n
Piszczek had moved to the German capital from his native land six years earlier, signing his first professional contract at 19.<\/p>\n
After two years of being a squad player in the Hertha attack, he finally made the right-back spot his own and his performances earned him a move to \u2018die Schwarzgelben\u2019.<\/p>\n
In his first three seasons, the full-back had won three major honours and had registered 25 assists in the Bundesliga for Klopp\u2019s men.<\/p>\n
<\/p>\n
Throughout those prime years, there were few better right-backs on the continent than Piszczek and he continued to deliver for BVB into his 30\u2019s.<\/p>\n
Although injuries gradually chipped away at his game time, the 66-time Poland international never failed to give 110% for the badge, leaving with 382 appearances to his name.<\/p>\n
His 11 years in black and yellow were something special.<\/p>\n
Dede – \u20ac3.3m<\/h2>\n
A man who arrived with a more glittering reputation, Leonardo de Deus Santos, better known as Dede, came to Signal Iduna Park as the Brazilian league\u2019s best left-back at just 20 years old in 1998.<\/p>\n
Arriving with the anticipation that comes with being a Brazilian footballer, the defender certainly lived up to that hype.<\/p>\n
Dede served 13 years in North Rhine-Westphalia, winning two Bundesliga titles; he played a key role in the first of those, playing 45 times as \u2018die Borussen\u2019 also reached the UEFA Cup final in 2002.<\/p>\n
The 2007-08 campaign saw the former Atletico Mineiro man register 10 Bundesliga assists from full-back.<\/p>\n
Just one international cap seems a disservice to a man who played 398 times for the 1997 European champions.<\/p>\n
