#4 Borussia Dortmund
After finishing a whopping 18 points behind Bundesliga champions Bayern Munich, Borussia Dortmund are in dire need of an upgrade in the summer. A squad filled with exciting youngsters and immature stars did not fire Thomas Tuchel to the heights he thought he’d get to. Now the German club are under Peter Bosz and his young Dortmund squad are craving a new leader.
Diego Costa is that leader. He’s a player that leads by example, his unrivalled intensity and work rate inspire those around him to follow suit. With Pierre-Emerick Aubameyang on the verge of completing a move to Paris Saint-Germain, Costa’s presence would fill the hole left by the Gabonese striker.
He has the clinical touch of Pierre, not the pace, but he offers a higher work rate out of possession. He’s the perfect figure to help Dortmund mount a title challenge next season.
