#4 Borussia Dortmund’s form
You could argue that Thomas Tuchel's side are heading into a Der Klassiker with the lowest confidence in a long time. The team have suffered some humiliating defeats in recent weeks to Bayern Munich, and AS Monaco on two occasions during their quarter-final exit at the hands of the Ligue 1 outfit.
Unfortunately for Dortmund, they bore the brunt of an unprovoked terrorist attack prior to their first-leg defeat at the hands of Leonardo Jardim's side. During the incident, star defender Marc Bartra was injured when exploding glass caused a laceration to his forearm which required him to have surgery.
This month alone has witnessed Tuchel come under intense pressure from many sections of the 'Yellow Wall.' Three defeats in a month are deemed not good enough, and with a lack of leaders within the squad, it's difficult to see Dortmund having the credentials to overcome Ancelotti's side.
