Heading into the summer, the fear among Dortmund fans was that they would be losing Pierre-Emerick Aubameyang to the Chinese Super League However, Neymar's sale from Barcelona to Paris Saint-Germain for a world record €222m has had all eyes on the future of Ousmane Dembélé. The French international has been a naughty boy over the last few weeks, skipping training at Dortmund and ignoring phone calls from manager Peter Bosz, as Barça continue to be linked. The reality of needing to find a...
Poaching the Youth Academy
Now, I know what you're thinking, the obvious choice to replace Dembélé is Christian Pulisic or Emre Mor, right?
Well, in short, yes. However, we've all heard the argument for the already Dortmund first team players to get a more permanent run out in black and yellow next season. So with a position opening up with the senior side, 18-year-old Jacob Bruun Larsen is ready to make the step up.
Although not strictly a product of the Borussia Dortmund academy, the young Danish winger left hometown side Lyngby in 2015 to move to the Signal Iduna Park. With an ability to play anywhere across the front three, Larsen has already made one appearance for the senior side in which he claimed an assist during a DFB-Pokal clash with Union Berlin.
Whether you've heard his name before or not, a truly outstanding record of 20 goals and 13 assists in just 17 games with the Dortmund U19 squad last season tell you Larsen is one of Denmark's stars of tomorrow.
Born in Catalonia
Although not a current Barcelona player, Keita Baldé Diao is a product of the coveted Barça academy.
Plying his trade with SS Lazio in the Serie A, Keita is a versatile Senegalese international who has just come off the back of an outstanding season in Italy.
Naturally a left-winger, something that will come in handy for when Marco Reus inevitably gets injured, Keita scored an incredible 16 goals in the league last season. A player who loves to drift into central positions, Keita's pace and power will mean he takes no time to adapt to Dortmund's fast, counter attacking style of play.
The Dembélé Formula
Considering Dembélé signed last summer as a relatively unknown 19-year-old from Ligue 1, Dortmund would be silly to ignore a potential star waiting for them at SM Caen.
19-year-old Yann Karamoh is one of the most exciting French players there is. Although he hasn't received the same level of exposure as the likes of Dembélé or Monaco's Kylian Mbappé, Karamoh has been attracting the interest of some of the biggest clubs in Europe.
Naturally occupying the right-wing spot for a side who just avoided relegation last season, Karamoh was directly involved in one quarter of all the goals scored by Caen last season.
When Dortmund signed Dembélé from Stade Rennais for a measly £13m last summer, no one knew he would become one of the best wingers in Europe, so why not try it again with Karamoh.
Although not quite at the same level Dembélé is at in terms of ability, Jesús Corona is a criminally underrated winger who should be playing in one of the top five leagues in Europe.
The Porto winger spent two years in Holland with FC Twente before making the switch to Portugal, having left Mexican side CF Monterrey in 2013.
Although Corona's involvement in 28 goals across two seasons is far from outstanding, his explosive speed and incredible footwork makes him one of the most dangerous players in Europe when the ball is at his feet.
Having a staring role in last season's 5-0 victory over Leicester City in the Champions League, his experience at the highest level of European football and continued staring role in Porto's domestic campaign means it's only a matter of time before the 24-year-old gets his break in a bigger league.
The Mini Messi
Turn the clock back to 2014 and any small Argentine you saw was being dubbed 'the mini Messi'.
Although we're a little less quick to jump the gun and laud praise onto a youngster these days, Atlético Madrid's Ángel Correa is one of the few players, that's been given the aforementioned Messi comparison, that looks destined to live up to the hype.
Another incredibly versatile player on this list, the 22-year-old has seen his development stall in the Spanish capital and despite Diego Simeone's best efforts at featuring the youngster as often as possible last season, Correa just doesn't appear to fit the Atlético model that Simeone has built.
Investing the Change
With the proposed fee talked about for Dembélé being roughly €150m, Dortmund can expect to have a fair bit of money left over should they be in favour of signing one of the players on this list.
Keita would likely be the most expensive player to sign from this list, although the Senegalese international would still leave BVB with close to €100m if he swapped Rome for Dortmund. So where could Dortmund reinvest that money?
Signing Roman Bürki for £3m from relegated Freiburg was a moment of genius from Dortmund in 2015. The Swiss stopper is an incredible talent but the idea of challenging for a Bundesliga title with Bürki in between the sticks isn't something many people can see.
Club captain Marcel Schmelzer, for all his quality, isn't getting younger. Raphaël Guerreiro was used more as an attacking player last season and after seeing the performance of new boy Dan-Axel Zagadou at left-back in the Super Cup, depth in that position is a cause for some concern moving forward.
