There are still about 5 days left before all teams in the UCL have to fight for a safe position and from the past few days we have only discussed Man City and PSG. On the one hand we forget that there is Madrid who might also fight hard against Salzburg. Then, are you sure Madrid can beat Salzburg and be able to get a safer position? Surely Madrid will easily get a win playing at home. While Salzburg is a team that is desperate and has no spirit and confidence to be able to continue its performance in the UCL. So I am sure Madrid will get the best position in the playoff round after being able to beat Salzburg.
You are right, it's just about some few days left before all teams in the champions League have to fight for a safe position and though Manchester City and PSG has been largely discussed , and real madrid are also team that is outside the qualification zone with just two matches to play namely Salzburg and brest am confident that real Madrid been the defending champions will surely qualify for the next phase of the competition, they will easily dispose both Salzburg and brest given to their squad depth and quality of players they surely will be the favourite when they meet.
