Sunderland climbed off the bottom of the Championship table with an impressive win over West Brom in front of prospective new manager Roy Keane.
Collins celebrates after heading in Sunderland's second
The home side's dominance was rewarded when Dean Whitehead's corner was missed by keeper Pascal Zuberbuhler and crossed the line before being cleared.
Neill Collins header extended the Black Cats' lead against an insipid Baggies.
John Hartson headed wide for the visitors but Sunderland easily held on for their first win of the season.
Keane met the Sunderland players during training on Sunday and his words seem to have had an immediate effect.
The Black Cats had lost their opening four league games of the season and they were propping up the table going into the game against promotion favourites West Brom.
But the roles appeared to be reversed at the Stadium of Light as Sunderland dominated and showed a renewed hunger and confidence.
Tobias Hysen missed from six yards out and Liam Lawrence headed wide before Whitehead's goal brought applause from Keane, who was sat in the directors' box.
Collins only increased Sunderland's euphoria when he headed in a corner just after the break.
Striker Kevin Phillips had chosen West Brom over a move back to Sunderland and was booed after coming on as a substitute.
He failed to raise a lacklustre Baggies as the home side comfortably saw out at the match for their first win of the season.
Sunderland chairman Niall Quinn:
"It's a great feeling. People thought we were going to get spanked again today so for them to perform like that, I'm very proud.
"The manager knows he's got characters in there. It was astonishing when you consider what they've been through.
"They impressed their new manager I would say. They won it the right way."
West Brom manager Bryan Robson:
"It was a shock to the system because we've competed so well this season, but we just didn't today.
"We were so ineffective in the first half I couldn't believe it. We got out-worked and out-fought and that is why you end up losing football matches.
"It was a bad performance and a bad day for us. Sometimes you can take defeat but the way we played disappointed me."
