Dortmund vs Freiburg (Asian Handicap) prediction

The odd with a such big asian handicap (AH +2) is irresistible for a bet. I think that Borussia Dortmund is over estimated at the moment because when you take a look at the recent results, it's not so good: 2W/2D/1L. Their victories happened during club friendly matches so it's not a real proof of their level. Their 2 last matches in Bundesliga against Wolfsburg (ranked 12th) and Hertha Berlin (ranked 11th) ended by a draw which enables me to consider that they're not in great shape. On the other side Freiburg just won 2:1 at home against RB Leipzig (ranked 4th) and previously draw in an away match against Eintracht Frankfurt (ranked 7th). Even if Borussia Dortmund is able to win this match, i think that Freiburg will defy pretty good and the spread by 2 goals or more is too big that's why i bet on a victory for Freiburg with an asian handicap +2.
