#2 The Jadon Sancho effect
In October last year, Jadon Sancho became the first 2000-born player to score a Champions League goal with a straightforward close-range finish against Atletico Madrid. Fast forward 13 months and the English teenager has continued to blossom for club and country, while seeing his market value skyrocket as he led the Bundesliga in assists (17) last term, helping Dortmund mount a serious title charge.
Despite suggestions the 19-year-old's head has been turned amid interest across Europe, Jadon has netted four goals and created seven more in Germany's top-flight already this campaign. His presence on the substitutes' bench made headlines ahead of kick-off as Lucien Favre claimed he needed "players on the pitch who are focused and ready."
Having watched the first-half from the bench, he was introduced to start the second and delivered another impressive display which will only continue to prove his status as Dortmund's scapegoat when their struggles clearly lie deeper than Sancho's situation.
European champions Liverpool, Chelsea, Manchester United and Barcelona themselves are said to be heavily interested in his services - with performances like these proving his worth as one of the world's best youngsters who continues shining despite ongoing tension.
When questioned after the game on whether Jadon should have started, Mats Hummels told Sky Germany: "I don’t want to talk about it. He played really well in the second half, was really involved and scored a great goal - that's the way it should be."
He was BVB's brightest spark and looked an ever-present threat, despite coming on in difficult circumstances with a two-goal deficit to overturn. Catching ter Stegen by surprise with a well-struck effort from distance, it flew into the top corner to give Dortmund faint hope of a comeback. If not for a fantastic stop by the German to tip his other strike onto the woodwork, we'd have been in for a grandstand finish.
