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.
There was a time when Brazil had super start players but right now i just know Neymar and i am not even sure what the entire team line up is and i do not give them a chance to lift the cup, i give Spain a chance here to lift the cup and i would rate Portugal as the favorites because of their performance in Euro, i did not expect them to win but they somehow managed and with Ronaldo in their team anything is possible and so does Argentina with Messi .
