Borussia Dortmund squad FOTO: www.bvb.de

Borussia Dortmund is the side with the least experience of this stage out of the four Champions League semi-finalists. The 1997 winners are now managed by Jürgen Klopp, and there is no reason to discount them as potential title candidates. They’re solid at the back, magical in the creation zone and have a terrific frontman in Lewandowski. Being paired with Borussia in Nyon is nothing to feel relaxed about.

League form: After taking back-to-back titles, Borussia have known for some time that they wouldn’t be making it three in a row this term. Following Bayern Munich’s triumphant march to the title, in which they won the crown with six games to spare, Dortmund have been focusing their efforts entirely on their European campaign, while second place in the Bundesliga looks a certainty.

Champions League form: Imperial. Despite being drawn in probably the hardest first round group, they ensured first place with some excellent home performances (1-0 against Ajax, 2-1 against Madrid and 1-0 against Man City). On the road they came close to wins in both Manchester and Madrid, as they also did in the knockout rounds against Shakhtar and Malaga. The game with the Andalusians produced one of the most dramatic finishes in the competition’s history, with two goals in injury time sealing qualification for a team that looked well and truly out of it. All in all, it’s a massive improvement on last season, when Dortmund failed to get out of a group shared with Arsenal, Marseille and Olympiakos.

The block: Solid. The yellow and blacks are a sturdy outfit in every department. Subotic and the injured Hummels (whose replacement Santana was such a hero against Malaga) provide soundness at the back, the midfield combines strength (Bender) and talent (Gündogan, Götze and the highly mobile Reus), and up front they have one of the most sought after strikers in Europe: Robert Lewandowski. They’re strong in the air and dangerous down the wings, where the Poles Piszczek and Blaszczykowski are in fine form. The weak points seem to be at left back (Schmelzer) and in goal (Weidenfeller).

The star: Mario Götze. Different. This is the central playmaker in the Dortmund squad, and highly effective he is too. He possesses exquisite skills, and has a wonderful understanding with Reus on his left, and also with frontman Lewandowski. His only failing, perhaps, is his lack of goals.
