In the Premier League! That's insane! Another little poser! Which team got relegated inspite of scoring over 100 goals in 1 season? Don't ask me when, I don't know the details, but our landlord asks us all every week when he's had a few!
I found something that says Man City are the only team ever, to have been relegated the season after winning the league. The season that relegation happened, apparently they still outscored every team in the division. It doesn't say how many goals that was though.
They are also the only team that has scored 100 and conceded 100 in the same season. I'm guessing all of this happened in that season!
According to the Football League table for that season, they finished 5th (with that goal tally you mention), there was only 22 teams in the league and you lot finished 21st Sheff Wed bottom.
And that was the decline of Sunderland. Up to that point we were one of the giants of English football.
