No way.
IMO, it's a no.
It's impossible because there are too many of them who facilitated the event.
It could be that the leagues, teams, players, refs/umpires, broadcasters, sponsors, and betting operators would all have to be deceived.
That scale of secret coordination is unlikely to be maintained without leaks in the first place.
So I dont think there's a fixed game in the major leagues.
That's right, besides the fact that they earn much more money in the major leagues, so it would be much more expensive to try to buy them. Apart from the fact that they are more visible and have a better reputation. As far as I can remember, the cases of match-fixing that have been caught in soccer were in secondary leagues, or if there was a specific match, the team involved was at the bottom of the table or near the bottom, never the top teams.
