It'll all change next week. Inter is doing really well in Serie A, and it's almost certain at this point that they'll win it. But I still think Man City is a better team, they are very consistent in the toughest league in the world.
Inter Milan are currently one of the best teams in all of Europe, they are flying in the seria A and they have the advantage over Atletico Madrid to progress to the QF. Having said that, i think we can start including Inter Milan as one of the favorites for the CL this season, they made it to the final last season, and i think they can do it again with how they are playing, mind you that Real Madrid and even Bayern Munich are not playing at their very best, thus this might be an opportunity again for Inter Milan to reach another final in two successive seasons, though i don't think they can be champions.
