Michael Chopra scored in injury time to give Roy Keane's Sunderland side a stunning victory over Tottenham on their return to the Premier League.
Chopra made the perfect start to life on Wearside
Substitute Chopra took a touch before firing home with almost the last kick of a game lacking in clear-cut chances.
Sunderland striker Daryl Murphy had earlier wasted the best chance of the game when he took a poor touch and was denied by Paul Robinson's legs.
Spurs had ample possession but Dimitar Berbatov wasted their best opening.
Chopra's winner on his league debut for the Black Cats was a dramatic end to a game otherwise almost devoid of incidents.
There was plenty of effort and enthusiasm from both sides but too many passes going astray.
It took 27 minutes before there was a shot on target, with Berbatov combining well with strike partner Robbie Keane, who shot weakly at Sunderland's new stopper Craig Gordon.
Murphy should have given the home fans something to cheer when a left-wing cross evaded everyone but the Irishman at the back post late in the first half.
But with just Robinson to beat his second touch let him down and when he finally got off a shot he could not beat the keeper's legs from a tight angle.
Berbatov was Tottenham's biggest attacking threat throughout and when Steed Malbranque picked him out with a pinpoint pass he beat the advancing Gordon before going to ground under a challenge from Dean Whitehead with the goal at his mercy.
Referee Alan Riley was not impressed enough to hand out the first penalty of the Premier League season, and Sunderland could have punished them further when they counter attacked and Dickson Etuhu was agonisingly close with a curling effort just past the post.
Robbie Keane was kept in check by the Sunderland defence
Sunderland were wasteful from set pieces while Tottenham's attacking threat simmered out after the break, with Paul McShane particularly outstanding at the heart of their defence.
Darren Bent and Chopra were given second-half runouts but it was Etuhu who looked to have blown the chance for the three points as he failed to control Ross Wallace's free-kick with the goal at his mercy.
It looked like it was going to be a worthy point for newly-promoted Sunderland until the ball fell to Chopra in the box and he took a touch before slotting low into the bottom corner to send the Wearsiders home happy.
Spurs boss Martin Jol, whose side managed just six clean sheets last season, will know they need to improve quickly if they are to realise their Champions League aspirations.
Sunderland manager Roy Keane:
"It's a great start to the season for us.
"The players did fantastically well and they showed great desire to win the game so late on for us.
"The whole group of players deserve a lot of credit. It's always nice to get points on the board."
Tottenham manager Martin Jol:
"We looked comfortable, but we didn't look creative.
"Our defence did well, but we have do better from the midfield, from the flanks and up front as well.
"A draw would have been disappointing for me. It was a boring game, but we couldn't even protect the draw."
