A few weeks ago, qualifying for Europe in any form seemed an unlikely prospect for Borussia Dortmund. On the back of a recent red-hot run, however – and a 4-2 win at second-placed Leverkusen last time out – the Black-and-Yellows head into the final matchday with a real chance of even making the Champions League. Should they do so, it would be an uplifting end to what has been a fairly chequered season.
