Archie Gray scored his first senior goal to secure a much-needed three points for Tottenham and under pressure manager Thomas Frank.
Spurs have now moved up to 11th in the Premier League, but are still seven points off the Champions League places, where they are hoping to finish.
Speaking to Sky Sports after the game, Frank hailed his side’s performance, saying: “Very important win.
“Clearly a game where desire beats detail. I don’t think we did a top performance. I like how we dug in, worked very hard, disciplined.
“I think we also managed to create enough chances. To come here and win 1-0. Very impressed with the players when things is not perfect, we did so many things right.
“We’re missing quite a few of the offensive players, so with that in mind it’s even more impressive.”
