As previously thought, Inter would take advantage of the home match to win in the first leg. Marko Arnautovic goal gave Inter Milan a 1-0 victory over Atletico Madrid, this result is certainly an important asset for Inter heading into the quarter-finals. Atletico were not able to do much in this match, Inter managed to lock them up with a very brilliant game. Inter's appearance this season is more competitive after reaching the Champions League Final last season. A performance like this is an important asset for Inter to win the UCL title, it is very realistic to be able to reach the final round again if they are able to maintain their performance.
Actually the victory over one goal is not really secure Inter Milan for second leg match, since home and away goals format in Champion League removing there are not really important when second leg match Inter scored goal against Atletico Madrid but they loss aggregate have to continue penalty kick. But not bad capital lead one goal and for second leg match Inter Milan can play full defensive and get match result draw have been enough for securing quarter final ticket.
Too early for predicting Inter Milan has opportunity will lead to final round in Champion League competition back to back because last season Inter got luckiness with easily opponent teams in drawing schedule since 16 of round until final round. I can't sure if possibility Inter Milan has to face Real Madrid or Manchester City in the quarter or semifinal round can defeat both strong team for qualifying to final round.
