We take a closer look at the many virtues that this Borussia Dortmund side has this season, they could compete for everything in Europe.The Borussia Dortmund board of directors have been doing things right at least for the last decade, they nearly conquered Europe back in 2013 with the guidance of Jürgen Klopp.They were in a small hiatus for a few years, but this season was key for them to get refreshed by many new talents and many well-established players are also responding very well to the challenge as Borussia Dortmund takes the Bundesliga by storm and does in the same fashion they have always done it historically.This is a squad that stays dynamic during the whole season, they always strive to practice the most offensive football one could ever hope for and they just keep discovering new talents every single year.The Dortmund supporters weren’t ever worried after Ousmane Dembele left to play for Barcelona, because the club’s scouting system is one of the best in the world and they quickly found a replacement who is even better than the Frenchman.We are going to talk about three key players who might transform this Borussia Dortmund side into a serious threat for any Champions League opponent they face this season.#SquadGoals pic.twitter.com/77NFtNAk8o— Borussia Dortmund 🇺🇸🇬🇧 (@BlackYellow) October 6, 2018Marco ReusBorussia Dortmund’s absolute leader, a man who has never left the institution that has always supported him when things got heavy for him.Reus has struggled with nasty injuries in the past, one even made him miss the World Cup in 2014 and prevented him to become a World Cup champion.The winger seems to be living a second youth before he turns 30 and he understands his role as the club’s frontman who should be good enough to take them very far in all competitions this season.He is the perfect role model for the generation of players who are also coming forward this season for the club, Marco Reus deserves to finally get this recognition as the leaders that he is.Paco Alcácer leads the Bundesliga in goals.He’s only played 81 minutes. 😱😱 pic.twitter.com/kOfGA2WHpn— FOX Soccer (@FOXSoccer) October 8, 2018Paco AlcacerWhen Spanish striker Paco Alcacer first arrived in FC Barcelona last season, he suffered from the same problems that other strikers go through when they compete every day against Lionel Messi or Luis Suarez.Merson believes Arsenal should sign Sancho Manuel R. Medina – September 14, 2019 Borussia Dortmund winger Jadon Sancho might be the perfect player to play for the Gunners, according to former England international Paul Merson.The Valencia CF product wasn’t able to keep up with any of both players and decided to leave, he took the offer from Borussia Dortmund and it didn’t really take him a long time to adapt.Today in the Bundesliga, Alcacer is the undisputed top scorer so far in the season and he was exactly the kind of striker that the German club had been craving for such a long time.With already 6 goals in the competition, there is no doubt that Paco Alcacer will finish his season with the highest goal-tally of his career.The #Bundesliga after 7 MatchdaysTop scorer:▪️@paco93alcacer: ⚽️⚽️⚽️⚽️⚽️⚽️▪️Minutes played: 8⃣1⃣Most assists:▪️@Sanchooo10: 👟👟👟👟👟👟▪️ Minutes played: 2⃣1⃣4⃣#bvb pic.twitter.com/OlbmdFm0pc— Stefan Buczko (@StefanBuczko) October 6, 2018Jadon SanchoArguably the greatest discovery that Borussia Dortmund has done since Robert Lewandowski first arrived at their doorstep, English lad Jadon Sancho is the biggest sensation in European football right now alongside French wonder kid Kylian Mbappé.The Golden Boy award will be disputed by the PSG star and this young player who already has 7 assists in all competition for Borussia Dortmund, which are more than any other player on the continent.Sancho just was called-up to play for his country in the next international break, it’s a dream come true for a player who is still too young and needs to take his career slowly.There are no guarantees that manager Gareth Southgate will give him the first minutes for England, but traveling with the squad so young is already a great achievement for the kid.Emotional. Inspirational. Unbelievable.Going into international break on a high note 🙌📰 https://t.co/m7qiJAH0Rh pic.twitter.com/dvfHEQE3Mx— Borussia Dortmund 🇺🇸🇬🇧 (@BlackYellow) October 8, 2018Which other players would you add to Borussia Dortmund’s best this season?
