Judging by Newcastle’s lap of honour at the end of this game, you would think it was the Magpies that had just been relegated from the Premier League.
You wouldn’t have thought this was a side that had just won 3-0 to secure a top ten finish, but parading around a stadium that was already more than half empty makes it clear all is not well at the club – the absence of Alan Pardew from proceedings telling.
Ole Gunnar Solskjaer’s team meanwhile have even more reason to be glum. The defeat ensures the Bluebirds will be playing Championship football next season.
On today’s performance, bouncing back at the first attempt seems a big ask for the Welsh club.
The home fans, meanwhile, unveiled banners calling for the sacking of boss Alan Pardew, with some supporters staging a walk-out.
Cardiff - who were without Gary Medel, Mats Moller Daehli and Kevin Theophile-Catherine due to illness - almost made an ideal start inside the first five minutes as Fraizer Campbell volleyed narrowly wide from the edge of the area.
Both sides struggled to create chances in the early going, but defender Mathieu Debuchy twice came close to giving Newcastle the lead.
However, the hosts did go ahead after 17 minutes, when Ameobi met Moussa Sissoko's right-wing cross at the far post with a fine diving header which flew past the helpless David Marshall.
Sissoko was heavily involved again as Newcastle narrowly missed out on doubling their advantage just two minutes later, with the midfielder's low deflected effort hitting the post.
Cardiff's main threat came through Wilfried Zaha, who would have levelled matters if not for a great reaction save from Tim Krul.
Both sides made a change during the half time interval, former Newcastle striker Craig Bellamy replacing Kim Bo-kyung for Cardiff, while Massadio Haidara took the place of Paul Dummett at left-back for the hosts.
But Bellamy's introduction failed to turn the game in the visitors' favour, and Cardiff were fortunate not to fall further behind as Mike Williamson saw an effort deflect just wide of the post.
A lack of excitement on the pitch saw attentions turn to protests off the field for much of the second period, but Cardiff found life in latter stages as they pressed for an equaliser.
First a point-blank save from Krul denied substitute Kenywne Jones a leveller, and Newcastle's lead was kept intact in spectacular fashion moments later as captain Fabricio Coloccini brilliantly cleared Aron Gunnarsson's effort off the line.
And Cardiff's fate was sealed three minutes from time, as Remy coolly finished off a Newcastle counter after collecting Sissoko's deflected pass.
Pardew's men then piled further misery on the visitors in injury time when substitute Taylor bundled the ball in from Remy's header, following good work down the right from Dan Gosling.
