On day two of the World Cup, we learned to expect the unexpected. MirrorFootball's Ed Malyon, Jim Daly and Richard Beech watched the action last night, here's what they learned from proceedings in Brazil.
1) You don't have to be Brazilian...
...to score a goal at the World Cup in Brazil. It took 150 minutes for a non-Brazilian player to register a goal at the 2014 World Cup.
Of course, Croatia had registered a goal within that time, but it was Brazilian Marcelo who put it in his own net.
World Cup match officials disallowed FOUR goals by non-Brazilian players before Peralta eventually opened the rest of the world's account in the 60th minute of the Mexico vs Cameroon match - the second match of the tournament.
His team-mate Dos Santos had two goals disallowed in the first half of the match. He was flagged offside on both occasions, despite being onside. He should be joint top scorer with Neymar.
2) Chile not at their best
Jorge Sampaoli's Chile have been a brave, buccaneering unit that presses the hell out of their opponents and hits them quickly on the attack like a lunging python.
Last night they were none of those things, and while they flew out of the blocks with two early goals it wasn't the side we are used to seeing.
There are probably a few reasons for that. Firstly, Arturo Vidal was a passenger with his injury affecting his ability to play with his usual energy. Hopefully the chance to play 60 minutes means he will be a bit fitter for the fixture with Spain.
Secondly, Sampaoli appeared to instruct his team not to pursue their usual full-pitch press. It may be because of the heat and his fear that to go hard at the Australians would have been an unsustainable strategy in the conditions, but it made them far less potent and didn't pin back their opposition. This played into Australia's hands and Ange Postecoglou's men were the better side in the second period.
How they line up against Spain will be intriguing, although it is – needless to say – a very different sort of test to the one they faced (and passed) tonight.
3) Mexico can do it on a wet afternoon at Das Dunas
The Mexicans controlled the game against Cameroon from the middle of the park, and passed the ball well despite the horrendous conditions in Natal.
The rain was coming down by the bucket load, but both sides put on attractive displays and the match was a far more entertaining spectacle than Brazil's clash with Croatia.
The tournament throws up plenty of fixtures you might be tempted to write-off at first glance, but don't fall into the trap of only watching the big teams.
The next match in this bracket is Ivory Coast vs Japan. Miss it at your peril.

4) Advance Australia fair
This was always going to be a learning experience for Australia, who have brought a young side to the World Cup looking ahead to the future.
Tim Cahill was right when he said post-game that the Socceroos showed a bit of fear in the early stages, but when they grew into the game they showed fight and dynamism – with only a slight lack of quality letting them down.
"At the start, we showed a bit of fear,” he said. “And then when we stepped up and started getting in their faces and rolling them a little bit. When they showed a bit of aggression, we have to show it back. We did that.
"We will learn from this and we will go into the next game very positive. We believe in our football, we believe in our structure.
"Last week they were questioning whether we could create chances. Tonight we created quite a lot."
Jason Davidson, Tommy Oar, Matthew Leckie and Ben Halloran were all 23 and showed what they could do, which bodes well for four years time.

5) Tiki taka is dead. Long live tiki taka.
Spain's patient build up and possession heavy approach - that has brought them so much joy and success over the last six years - was no match for Holland's pacey counter attacking.
Matched with the physicality of the likes of De Jong the New Dutch style (a sort of super charged Total Football) proved far more effective. Spain looked out of touch and confused. Maybe it's time to give up on the tiki taka?
6) You take the high road
Marcos Gonzalez's absence from Chile's squad robbed them of their only real central defender, and with the pint-sized Gonzalo Jara and Gary Medel now charged with anchoring the back line there is a real vulnerability to aerial attack.
Australia caused numerous problems simply by getting aerial balls to Tim Cahill, and on top of the headed goal just before half time he arguably should have had two more.
For Spain, the question is how they make the most of this weakness when they are so used to playing it on the floor. Diego Costa is over six feet tall and physically imposing but he's not renowned for his aerial ability. That said, with Jara and Medel he may not need to be exceptional in the air to cause enough of a disturbance.
Marauding full-backs have always provided Spain's best width, but perhaps it may be worth playing a genuine wide player like Pedro ahead of David Silva or Andres Iniesta as part of that front three. It is possible that neither would need to be forfeited if Vicente del Bosque makes an attacking switch in midfield and drops Iniesta in for one of Sergio Busquets or Xabi Alonso.
Sergio Ramos' potency at set pieces should also not be ignored.

7) Don't upset the locals
Diego Costa's decision to snub Brazil in favour of playing for the World Champions was not taken well but the locals in Salvador. They booed the Chelsea striker every time he touched the ball (which wasn't many).
Maybe they should be thankful he didn't opt for Brazil as he had a torrid time and was replaced my Fernando Torres. The home fans did, however, love the stylish goals from Van Persie and Robben as the Dutch ran riot - perhaps anticipating a mouth watering clash between Holland and the World Cup hosts later in the tournament.

8) Netherlands aren't a write-off
In hindsight, the notion of football fans clambering over each other to pronounce the Netherlands side as being no-hopers, and having an imbalanced mix of arthritic veterans and wide-eyed schoolboys, is actually somewhat cringeworthy given what happened last night.
But we got the Spain thing right, so let us off? Concerns over the form of Van Persie and the fitness/fragility of Robben have been put to bed. Netherlands are very much in this, and if you took a long-shot on the Dutch to win the tournament, then you probably got great odds.
You won't get such great odds if you want to place that bet this morning.
