What is the world record for:
- Most goals scored by one team in a game?
- Most combined goals in a game?
- Most goals scored by a team in a season?
There is some confusion about the score at the end of the match since the score board shows 32-0 but:
At the end of the match, the scoreboard at the stadium showed a 32–0. Only after the statistician did a recount, the 31–0 scoreline was announced, After the match, FIFA went on to release the official statistics after receiving the official report from the referee and match officials, which confirm the 31–0 scoreline.
As for your third question, it is very hard to answer it because it can include trophies? can it include friendly games? can it be at any league level(for example english fourth division)?
the most league goals scored in a season I found was 134 by Peterborough United at english Fourth Division, 1960–61 season. (Source)
