Atletico Madrid's performance against Inter Milan was not that good yesterday. Atletico Madrid managed to have seven attempts with no shot on target, which even made Inter Milan's goalkeeper more relaxed. If Inter Milan can stop Atletico Madrid from scoring in their return match, I think Inter Milan will qualify for the quarterfinals of the UEFA Champions League.
Now you can think like that, but Atletico Madrid themselves will also make a little evaluation of themselves before they play the second leg match with Inter Milan. Because Atletico Madrid also won't want to be complacent about the defeat they experienced in the first leg yesterday, so the second leg could quite possibly be a very fierce match for them in order to qualify for the next round even though Inter Milan themselves already have a little capital which they got yesterday in first leg.
I know it is not easy to win against Italian clubs at their home ground, but Atletico Madrid could have done better against Inter Milan yesterday. There is hope for Atletico Madrid to qualify for the next round of the UEFA Champions League if they improve their performance when Inter Milan visits them at home and also defeat them by two goals to nothing.
