Borussia Dortmund, Chelsea, Ajax and the most unlikely Champions League finalists ever

Where do Dortmund from this season rank on the list?

Well, who could have seen that coming? Borussia Dortmund are Champions League finalists after their 2-0 aggregate win over Paris Saint-Germain. But is their presence at Wembley the unlikeliest of the Champions League era (we're skipping over the European Cup when participation was so radically different as to open the door for all sorts of surprise finalists)? Let's find out:

With all due respect to the Liverpool side of 2004-05, a Steven Gerrard howitzer away from elimination, this was the English champion that really shouldn't have been. Having fumbled their way out of a fairly simple group, it was no great surprise when a side utterly at sea under Andre Villas Boas were tonked 3-1 in the round of 16 first leg against Napoli, a defeat that cost the Portuguese boss his job. Had Roman Abramovich really believed that the season could be salvaged he might not have appointed former Blue Roberto Di Matteo, whose managerial CV beforehand largely encompassed promoting and relegating West Bromwich Albion.
