Dele Alli scored a first-half penalty for Tottenham Hotspur to make it a winning return to Molineux for former Wolverhampton Wanderers head coach Nuno Espirito Santo.
Spurs broke the deadlock on 10 minutes when midfielder Alli side-footed home from the spot after being fouled by Jose Sa.
Raul Jimenez, making his first home Premier League appearance since 23 November 2020, went close to equalising after 27 minutes but fired narrowly over from Joao Moutinho’s low square ball.
Nelsen Semedo fired narrowly over and Trincao and Jimenez were both denied by Spurs goalkeeper Hugo Lloris, while Steven Bergwijn and Son Heung-min went close for the visitors as the teams traded second-half chances.
Spurs substitute Harry Kane, making his first appearance of the season, nearly made it 2-0, but his 81st-minute effort was saved by Sa.
