Seeing the odds given by bookies is more profitable for Sporting which has lower odds than Dortmund,it is possible because Sporting will play as the home team in the first leg but Amorim's departure has made Sporting's performance decline drastically in the UCL because they have not won since Amorim left so I prefer Dortmund who will most likely qualify for the last 16, because I saw Dortmund win their last game with the new coach.
I will put Dortmund ahead. Sporting had a good start to the Champions League. Even the top spot in the Liga Portugal table is still in Sporting's hands. However, Sporting has failed to win in the last four matches of the Champions League. Sporting has lost three matches and drawn one.
However, Sporting won 4-1 against Manchester City in this year's Champions League. However, when this happened, Amorim was the coach of Sporting. So the possibility that Sporting will be able to play well and win in the match against Dortmund is somewhat low.
Although Dortmund's performance is irregular. However, it seems that Dortmund is very serious in the Champions League matches. Dortmund is able to play quite well in the Champions League.
