I know that Germany is a much bigger team like Spain, France etc. but we cannot say this that it would regain this title as they have it four years before. In last world cup, Germany was quite lucky because the playmaker of Brazil; Neymar Jr was not playing the final and without him the team is nothing as it was proved when Germany beaten Brazil by 7-1 but this time, he is playing the matches.
You cannot say that one player alone will make the entire team win. Yeah he may be in form, but so was Sane. He got left out of World Cup because he hasn't had a good performance in an International Match.
And what about the big names from the NT that didn't make it? I can name you a few world class players + some others that are missing the WC and even get a starting XI: Oblack, Antonio Valencia, van Dijk, Bonucci, Alaba, Vidal, Verrati, Bale, Alexis Sanchez, Insigne, Aubameyang.
Are you serious? No Bale? No Bonucci? What the heck? All these players are damn good! This is much worse than it looks like.
Man, these world cups come once in 4 years, and a few people want to fuck up the future(potential) of good players.
