Boki Ar: Like Americans (apparently), I'm also mostly ignorant about soccer -but I have a question for you for which I have never had a confident answer: Consider this scenario:
A "penalty" is awarded by the umpire that involves a throw-in from the corner of the playing field (the corner where the goal thingy is in your picture). The player tosses the ball towards the goal and it passes a number of the opposing players (so not off-side) and eventually it hits the net. It's not touched by anyone and it's admittedly a highly improbable scenario - but, is it a goal?
There is no penalty that involves throw-in's in football, AFAIK. Penalty shots are from the front of the goal.
If a ball leaves the pitch, there are three ways that it can return to play:
1) If it crosses a side line, the team that *didn't* touch it last throws it in from the sideline at about the point it went out. This is the only throw-in in football.
2) If the ball crosses the back line and the offense was the last person to touch it, it is a goal kick. The defending goaltender gets to free kick it from inside the goal box area. (Insert Hope Solo ZIKAaaaaa!!!! crowd cheer sound bite here.)
3) If the ball crosses the back line and the DEFENSE was the last person to touch it, it is a corner kick (As Boki Ar's video above illustrates). The offense gets to kick the ball from the nearest corner, placing it anywhere within a small arc that doesn't 100% preclude hitting the net with a lucky shot or one with enough spin to "bend it like Beckham" as footballers say.

This web site talks about what happens if a sideline throw-in goes into the net:

Basically, the thrown-in goal does *not* count, and results in the offense getting a corner kick to essentially try again.
Disclaimer that this is coming from an American, and we know zilch about international football.
vreihen: No disrespect intended to the locals, but what's so special about San Diego?
Being close to Mexico, they have the best tacos?
There will soon be a hiring boom for construction workers to build Trump's wall?
That silly naval base where they keep all the
nuclear wessels that aren't in Alameda?
Seriously though, that's where the game was taking place. It is a huge deal in Serbia, but the only advertising for the game here was probably on the marquee outside the stadium.....
