You did not mention which of the Madrids is going through, Real or Atletico?
Atletico Madrid will qualify. Just kidding. 
. It has been updatedQuote
even if Arsenal should start with the young boys.
It could happen and Arsenal will keep their core players. Even if they play with young players and lose, it will not change Arsenal's fate and they will still qualify.My predictions for today's games
Lille - Borussia Dortmund (Lille will win)
Atletico Madrid - Real Madrid (Real Madrid will win)
Aston Villa - Club Brugge (draw)
Arsenal - PSV Eindhoven (draw)
Looks like Dortmund is making a comeback bro, the current score is 1-2 with an aggregate score of 2-3. Very bad. Lille - Borussia Dortmund (Lille will win)
Atletico Madrid - Real Madrid (Real Madrid will win)
Aston Villa - Club Brugge (draw)
Arsenal - PSV Eindhoven (draw)
In the Arsenal match I have an assumption that Arsenal can lose in this match. Because even though they lose, Arteta is very safe to be able to continue the match to the next round. But if all bettors assume Arsenal will lose in this match, I am sure the result will be the opposite and be a draw as you predicted.
