It might seem strange to some, but despite the Olympic opening ceremony not even taking place yet in Rio de Janeiro, the Olympic Games have already begun.
The opening ceremony is set to be held this evening as they officially welcome the Olympics to South America, but that's coming after game-week one of the football has already taken place.
The women kicked off their tournament on Wednesday, and the men started their group matches yesterday, with the host nations Brazil taking on South Africa.

Given the amount of talent at their disposal, with the likes of Neymar and Felipe Anderson, Brazil are expected to take home the gold in the football, but things didn't get off to the best of starts for the hosts.
Despite South Africa going down to 10-men near the hour mark, Neymar and co. couldn't find a way through their resilient defence, and had to settle for a point in a 0-0 draw.
As the final whistle blew, the Brazil boys were met with boos from those in attendance, and given how the last football tournament went for them in their home country, you can see why the locals were not impressed.
Neymar spoke after the game saying how it wasn't nice to hear his own fans boo him and his teammates, but he also said he understands why they chose to do so, admitting the team's performances was not up to scratch.
The Barcelona star was one of the players that got most of the criticism in the post-match fallout, mainly because he is Brazil's poster boy and everything positive on the pitch is expected to come through him.
Football fans across the world were quick to judge Neymar's performance on Twitter, heavily criticising him and seemingly having fun at his shortcomings.
Here you can see just a select few of tweets aimed at Neymar in the wake of Brazil's goalless draw with South Africa.
Up next for Neymar and his teammates is a clash with Iraq, before they end the group stages by facing Denmark.
