How is this possible?

Keeper Guilty of Moving Goalposts
IFK Gothenburg goalkeeper Kim Christensen could be in hot water after moving the posts during a Swedish first division game to make the goal smaller. The Danish goalkeeper was caught by TV cameras pushing the posts toward each other before a match against Orebro.
Referee Stefan Johannesson spotted the posts had been moved a few centimetres about 20 minutes into the game and pushed them back into the right place.
Christensen later said he had done the same thing before several other games.
He was spotted using his feet to push the bottom of each post slightly inwards.
The Swedish Football Association is investigating the incident.
"I have never heard anything like this before," said Swedish FA's disciplinary chief Kheneth Tallinger. "It's unique."
IFK Gothenburg drew 0-0 with Orebro and top the table on goal difference with just a few weeks of the season to go.

How did he do that? Surely it must be quite hard to move goalposts...

I don't think they are into the ground like over here.

You can tell from the video.
