This bet is too big to ignore in my opinion. The odds for this were lower against the bigger Bundesliga teams like Leverkusen/Leipzig which I view to be of at least the same quality as Ajax and were even priced lower against Bayern Munich in August in the Supercup. While Dortmund have certain injuries, big players like Haaland, Reus, Hummels, Bellingham etc. are all expected a start in this game. Especially Haaland has been in exceptional form and should be able to move this line lower down on his own in my opinion.
