I think group stage will be very difficult for each team because they are quite competitive and focused. Maybe Germany has a chance to survive group stage this time because its group is not that strong and it has home advantage but Spain will be a huge challenge. They are playing a better ball also because of Tiki Taka. Sadly I did not get my hands on any tickets for the German matches.
Italy is also playing a good ball and France has Kyliaan M'Bappe so you know what that mean.
