Ameobi has been a peripheral figure on Tyneside since the emergence of Cisse and Demba Ba but was glad to remind manager Alan Pardew of his all-round capabilities.
"As a striker you want to get off the mark as quickly as possible at the start of the season," he told ESPN.
"I'm just delighted to get a chance there today. The strikers at the club are doing very well at the moment and I have to take my chances when I get them.
"I just thank God that the chance fell to me and I couldn't have scored an easier goal. The team were fantastic."
