Newcastle’s dramatic 4-3 defeat to Manchester United at Old Trafford.
With the score level at 3-3, the 2nd half substitute had the chance to put the Magpies in front for the fourth time and perhaps seal victory at the ground of the Premier League leaders for the first time since 1972.
But the 20-year-old’s shot struck David De Gea’s post, with United’s Spanish goalkeeper beaten.
“I just cut in and hit it – I scuffed it a little bit, and it rolled on to the post,” Ameobi told The Shields Gazette.
“I was just hoping it went in, but it didn’t.
“I was anxious to play my part. I got my chance, which I’m grateful for, but we just couldn’t nick a win or a point.”
And Ameobi said the players were “devastated” at the final whistle after Javier Hernandez had been left free to slot home an injury-time winner for the Red Devils.
“It was unfortunate that towards the end, our defending wasn’t 100 per cent. It was just unfortunate, really.
“Everyone was devastated in the changing room, just as much as all the fans.
“They gave us great support, and it was unfortunate we conceded,” he added.
“Obviously, we played great football, and the goals came from good running and good passing into the box.
“But we conceded some bad goals as well.
“Had it not been for that, we could have come away with three points.”
