The 28-year-old scored his debut goal for Black Cats in the 3-0 derby win over Newcastle United on Sunday.
"I'm absolutely made-up to score. I always have that self-confidence going up for set-plays that I might get the second ball. I've been close a few times for Sunderland, last year and last week as well," Jones said, as quoted by the Daily Mail.
"It's huge for us. It's a derby game, so you want to win to make it six-in-a-row. You want to do it for the fans, do it for the club and have the bragging rights.
"But to get our first win of the season is massive and we needed to get that pressure off ourselves."
