David Moyes hailed his heroic players and man of the moment Victor Anichebe after the striker inspired Sunderland secured their first win of the season.
His first victory as Black Cats boss was clinched against the odds at Bournemouth after the bottom-of-the-table side were reduced to 10 men just before the hour.
Midfielder Steven Pienaar saw red after receiving his second yellow card for a challenge on Junior Stanislas.
It looked an uphill battle but when Adam Smith pulled down Anichebe in the box, Jermain Defoe marked his 600th career game by firing home the 74th-minute winner from the penalty spot.
For Anichebe it was a memorable day after he hammered home the 33rd-minute leveller after Dan Gosling had put the Cherries ahead in the 11th minute.
Sunderland held on in the dying stages, with Jordan Pickford making a stunning save high to his right four minutes from time from Josh King.
Moyes was delighted with his side's display, highlighted by an excellent first start for Anichebe, who he signed AFTER transfer deadline day when the ex-West Brom striker was out of work.
"I always thought Victor has great ability and a lot more than people give him credit for," said the boss who revealed the 28-year-old suffered a cracked rib in the first half.
"He's strong, quick and good in the air, he doesn't always show it I'll admit that, but he did today, that was for sure.
"He played very well and scored a good first goal made the second goal."
The players showed tremendous character after seeing Pienaar dismissed by referee Mike Dean.
Sunderland needed to dig in and that's exactly what they did at Dean Court against a side unbeaten at home since the first weekend of the season.
"For 10 minutes [after the sending off] we got paggered," said the Scot. "Bournemouth had two or three very good chances.
"There have been a couple of games that I don't think we've had a lot going for us, like West Ham late on, Crystal Palace on.
"But we maybe did have it going for us today."
