Forest's plight has been self-inflicted but there is still more unity than in north London.
Thursday's penalty shootout win at Midtjylland earned them a Europa League quarter-final tie with Porto, edging them closer to an early-season goal of winning the competition.
That was before four permanent managers this season - Nuno Espirito Santo, Postecoglou, Sean Dyche and now Vitor Pereira - which underlines the turbulent campaign at the City Ground.
Nuno fell out with global sporting director Edu and owner Evangelos Marinakis, leading to his sacking, while replacement Postecoglou lasted just 39 days.
Dyche never won over the players in his 144-day reign, leading Marinakis to recruit ex-Wolves boss Pereira in February, having worked with him at Olympiacos.
Despite the revolving door, Marinakis retains the support of the fans - in contrast to Spurs - with the club also having frozen season ticket prices.
"I'm sure the ownership - they're not stupid - will be looking at what the solutions are to the off-field problems," said James Bogue of the Nottingham Forest Supporters' Trust (NFST).
"But nobody can argue it's not been self-inflicted. Nuno didn't get the new players that he wanted and it's all fallen out from there.
"The lessons will - and must - be learned, that you've got to get everything lined up on and off the field right."
Yet this campaign should have been the platform for Forest after last season's seventh place.
They missed out on reaching the Champions League on the final day in May, then spent £180m in the summer to try to keep pace at the top.
Few have made an impact, with £26m striker Arnaud Kalimuendo shipped to Frankfurt in January, and the loans of Douglas Luiz and Oleksandr Zinchenko cancelled.
James McAtee and Dilane Bakwa, signed for a combined £60m, have made four league starts between them.
Forest could not have expected Chris Wood, who scored 20 goals last term, to miss the majority of the campaign with a knee injury, but despite the chaotic season Bogue believes fans would not change the ownership.
"Their ambition shines through," he said, with Forest having been promoted in 2022 after 23 years outside the top flight. "We love it. The ambition has taken us from the foot of the Championship to a team in Europe.
"Missteps have been made and it's a season which has fallen flat, but what do we want?
"Do we want owners who are not ambitious, who want to sit 13th and 14th, or do we want to strive higher? I'd go with the latter."
