Germany's strong showing in its opening match is not much of a surprise. The Germans have won seven straight World Cup openers by a combined score of 27-3. Portugal, on the other hand, suffered its worst World Cup loss in six appearances with the 4-0 defeat.
Here are five notes on the first two games of the day:
* Germany is the first country to score at least four goals in four straight openers, including its eight goals against Saudi Arabia in 2002, which is the most Germany has ever scored in a World Cup match.
* Thomas Muller posted the 49th hat trick in World Cup history and the first by a German since Mirolav Klose netted three against Saudi Arabia in 2002. Those three scores marked Muller's sixth, seventh and eighth career World Cup goals. At 24 years, 276 days, he is the youngest player in the last 40 years to score eight World Cup goals and the fourth youngest overall to reach that mark.
* Mats Hummels scored his nation's 36th headed World Cup goal since 1966, extending the massive gap between the Germans and Italy's 19, the second most over that span. Hummels is one of 17 players to have scored their first World Cup goal so far at this tournament.
* Portugal finished the match with eight scoring chances created, but no goals to show for it, whereas Germany created six chances and converted four (one of those being a PK). Cristiano Ronaldo finished with seven total shots (two on goal), tying Karim Benzema for the most in a game at this tournament. There are 16 players with two or more shots on goal at this tournament and only four have failed to score (Ronaldo, Izet Hajrovic, Mark Bresciano and Arthur Boka).
* The second match of the day ended in a 0-0 draw between Iran and Nigeria, the first draw of the tournament, coming in the 13th match. Twelve matches without a draw is the longest streak since 1930. Iran earns its first point in its four openers with the draw and is winless in its last five World Cup matches overall. Nigeria is winless and scoreless in its last three openers and is winless in nine straight World Cup matches overall (0-6-3).
