In the second leg, Dortmund must try harder to get a win in the deciding match. A draw is not good enough, but looking at the performance of both teams, it is considered fair and quite satisfying for both teams. But in the second leg, of course, everything will be different, Dortmund might be able to get a win with their full effort. I hope to see a really all-out match from both teams in the second leg.
If you look at the appearance of both in their respective Leagues, it is not much different so it is still quite difficult to predict the course of the match in the second leg. Lille is more advantaged by the draw obtained when playing in the first leg so that the game in the second leg will take place at home. In terms of pressure, Dortmund may be much greater, but anything can still happen. Hard work will determine the results and if the coach has a better strategy then one of them still has a good chance of winning, although Lille itself is much more advantaged playing in front of their own audience.
LOSC is a team that is quite tough to beat so for Leg 2 later the chances of both Dortmund and LOSC are still 50:50 even with Dortmund instability being my concern that they will be eliminated later. Then some teams that have pocketed 80% to qualify such as Arsenal, Bayern Munich and Aston Villa while the remaining teams with thin aggregates can still be considered to turn things around in Leg 2.
