Ings, coming on for Leon Bailey, found Watkins with practically his first touch with a seeking ball from the left and his fellow striker took advantage of a Brandon Williams slip to put Villa ahead after 41 minutes.
Ings scored himself in the closing minutes of the game to double Villa’s lead with a sharp spin and shot.
Norwich needed to avoid defeat and hope Burnley didn’t beat Watford to avoid going under. However, late goals from Jack Cork and Josh Brownhill gave Burnley a 2–1 win and doomed Norwich to the Championship after a season back in the top flight.
“I’m disappointed with our result. It’s probably fair, we haven’t been good enough this season,” said Norwich captain Grant Healy.
“It’s difficult for me to comment on something now. Emotions are high, we gave everything but it wasn’t enough and the story of our season.
“It’s important not to look too far ahead, we still have pride to play for. Then we’ll see where we stand.”
Norwich spurned a golden chance to equalize two minutes after Watkins’ goal when the unfortunate Williams headed over his head after Grant Hanley nodded back a Norwich free-kick across the box.
Bailey, who limped off injured just before half-time, almost gave Villa the lead with 20 minutes left but his snap from just outside the box was touched by the outstretched Tim Krul on the crossbar.
Villa’s attacking trio of Ings, Watkins and Philippe Coutinho rushed in after the restart at Norwich, with Ings nearly doubling the lead in the 51st minute only to see his attempted chip blocked for a corner which he then threw at the Latte beheaded.
Norwich ran out of breath as the game progressed and he barely got out of their own half at the end as Villa increased the pressure before Ings put the shine on the goal line well into injury time.
Villa’s first win in six games put them 13th on 40 points, while Norwich are bottom on 21 points.
