The England striker opened his account for the season against Manchester City, but was quick to point to the performance of his young teammate.
Gooch made his first league appearance for the Black Cats against Pep Guardiola's side, and looked a threat in his 65 minutes on the pitch, leading Defoe to applaud the 20-year-old's performance.
“Gooch came in and he was fantastic," Defoe told safc.com.
“He’s strong, he’s got legs and he didn’t look at all fazed or nervous, and it’s a massive game to come into so you’ve thrown him in the deep end but he’s performed.”

Another positive for David Moyes was the performance of Defoe, with the 33-year-old hotshot starting the new season with the same attacking potency as he demonstrated at the end of the previous campaign. He fired home the goal that looked like it might earn the Black Cats an unlikely draw, only for debutant Paddy McNair's unfortunate own goal to deprive David Moyes of an impressive draw at the Etihad.

The Northern Ireland international was one of three new signings to pull on the Sunderland jersey for the first time, with fellow Manchester United graduates Adnan Januzaj and Donald Love also featuring.
But though there were plenty of positives for the Wearsiders to take away from Manchester, Defoe certainly echoed the feelings of supporters by highlighting Gooch's performance.
