It’s good that this is only the first match and this penalty was not decisive. I think that a draw in an away match is not the worst result, of course they would like to win away, but after this match PSV is in a more difficult situation, since the match in Germany will definitely be more difficult for them. This is not the first time that a referee's error has affected the final result. In the second match, Inter managed to beat Atletico, I didn’t expect that they could win, I expected that the match would end in a draw. Now Atletico will have to correct the situation in Madrid...
Regardless of what happens, the final result 1-1 is very profitable for Dortmund who will play the second leg at home.
PSV has actually made maximum efforts but the quality of the Dortmund team is slightly better than PSV so the results of this series are not surprising. I don't know why the referee killed that game by awarding that controversial penalty to PSV, but these things happen in football and we have to take it that way. But am sure the Dortmund coach and staffs will be more happy that they didn't lose the entire points in this game.
And for the Inter Milan vs Atletico Madrid match, it was very fierce, even though Inter Milan won the match, they couldn't completely calm down because they only had a 1 goal lead, making it possible to be chased by Atletico who will play at home in the second leg.
The outcome of yesterday's game is still Favourable to Dortmund who have the chance to win the second leg in the own stadium. Their performance yesterday was really good and if they can play like that in their home they will definitely qualify
