DORTMUND — Borussia Dortmund has never beaten Barcelona . They have won three of their five matches and drawn the other two. Four months ago, they claimed a crucial victory at the Westfalenstadion in the Champions League group stage . They are now looking to build on their 4-0 first-leg victory and reach the semi-finals of Europe’s top competition for the first time in six years.

Hansi Flick’s Barcelona are approaching the crucial moment of the season enjoying their best form. With 24 matches unbeaten , the club’s fourth-longest run in history, the message Barcelona is sending is that nothing is off the table thanks to a style of play that continues to surprise both inside and out, and which the coach is keen to confirm in Germany.
