The Canaries found themselves back among England's elite courtesy of their Championship play-off win in 2014/15 and there was an air of positivity surrounding Carrow Road.
Young manager Neil had overseen a stunning run of form heading into the top flight campaign and things were looking ok after the first six weeks.
But the Norfolk outfit won just four of 22 between mid-October and mid-March which ultimately sealed their fate, as did five defeats in their final six outings.
Summer arrivals Dieumerci Mbokani and Robbie Brady plus winter additions Timm Klose, Ivo Pinto and Steven Naismith were passable, while youngster Nathan Redmond was a shining light, but it was a distinct lack of quality over the entire squad which led to Norwich's downfall.
Neil is expected to stay on in the role next term and will need to make some astute signings in the next transfer window if he wants to resurrect this slide and fire the Canaries back into the top 20 of English clubs.

FROM THE BOSS
"If they've got any sort of professional pride then it shouldn't be tough. Certainly for the 2,000 fans that have travelled up, the least they deserved was for every player to give their all.
"If everybody wants to call themselves a professional football player, the first part's the essential part - professional.
“I think regardless of what game you're playing, you should be up for it 100 per cent."
- Alex Neil, May 2016
*Thanks to Opta
5 – Norwich kept just five clean sheets this season in the Premier League this season, a league low figure. Porous.
