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.
I did not expect Lille to be that tough to a team like Borussia Dortmund that have tested the champions league final in recent times. I saw the signs that Lille is not a small team when the disgraced Feyenoord by six goal to one. Even against Dortmund, they played so well and when they were one goal down, they never gave up but were determined to score and they eventually scored and avoided a loss. Borussia Dortmund will be visiting them in their base where they are strongest. If Dortmund do not take time, they will be eliminated from the tournament.
