World Cup 2018: Powerhouse teams showing weak spots

Five days in and the 2018 World Cup has lived up to expectations, even delivering a few surprises.David has not quite slain Goliath here in the 2018 World Cup. The giants have taken their licks, some have been brought to one knee, but for the most part they're still standing.
The underdogs are certainly closing the gap, though.
Soccer is normally a sport in which we see a lot of 1-0 and 2-1 results. It's part of the beauty of the game, in which a single goal by a team can propel them to an upset.
Fourteen matches have been played through five days, with eight of those decided by one goal.

Close wins were also on tap for many of the favorites. France knocked off Australia 2-1, a game that featured the first use of the V.A.R. system. The video-replay-assistant is being used for the first time in World Cup play.
England also had their fair share of struggles in a 2-1 victory over Tunisia. Despite an edge in shots, 17 (7 on goal), and possession (60-40), it took a stoppage-time goal by Harry Kane -- his second of the game -- for England to pull out the victory.
Then there's the story of three favorites, including defending champion Germany. The Germans became the third-straight winner of the previous Cup to lose their first match. Now the upset isn't one of epic proportions -- they lost 1-0 to Mexico -- but the result caught many by surprise.
Mexico, meanwhile, got the start to the Cup they were looking for. El Tri picked their spots to sprint with Germany and used multiple missed opportunities by the Germans (25 total shots) and excellent game by goalie Guillermo Ochoa (9 saves) to pick up the victory.
A bigger shock was Brazil playing to a 1-1 draw against Switzerland. Also owners of a 1-1 draw was Argentina, who failed to defeat first-time participant Iceland.
Iceland fights onThe dance of the underdog is oft-told tale. A person, a team, a country who isn't supposed to even be in contention rises above the rest. In the process, they win the hearts of not only their fans, but of so many more.
It's only one game, but it's safe to say Iceland has done exactly that.
