Aberdeen will look to try and keep this tie alive and bring it back to Pittodrie again this is another match that suits the criteria I have for betting under, 1st leg of a European match and hot weather, of course, Aberdeen will try and get an away goal but they will largely play with men behind the ball and hit Rijeka on the break, on the other hand, Rijeka will not want to give up the away goal and added to that the weather we could see a nice slow-paced match. I am a little concerned with the Aberdeen defence however I think they may not be exposed by the midfielders pushing forward so I am happy to bet the under.
