I also don't understand that point of view. People are looking at only what happened at the end. Yeah it wasn't a good ending for Inter in the Serie A and Champions League. But these guys were still one of the most successful 2 teams in both tournaments. 
Actually nobody can dispute Inter Milan from being a successful team even as they missed the two trophies and they wouldn't be far from the third best successful in the whole Italian league currently and there potentials has not left them yet because they would always go to every season with confidence of what they have and could give, actually even if Inter Milan was messed up by PSG but from the clubs they sent home before getting there they're definitely a successful club but just like other teams has ones fall and rose to become champion, Inter Milan will not be exempted from it because they might also rise again to winn.I don't know why you guys are giving credit to a team that is as worst as arsenal hu? How can you explain someone giving up a league title for a champions League title, they knew too well if they have given their best in the league title they would have won it but yet they chose to put more energy on champions league, that is more less of a person that pour away he's water in a water jar hoping for a rain drop just because the clouds was stormy now no rain no water, now they are only guarantee of a ucl competition going home trophyless to me I'd say it's unwise, what makes you successful at every end of a season, is it coming out as a runner up or coming first with a gold medal, to my own opinion they disappointed me and someone of their fans, it trophy that makes you successful not how good you play, spurs are more successful than inter Milan this season. That's my takes on this
