Paolo Di Canio felt his Sunderland players performed like 'warriors' as they claimed a 3-0 derby victory at Newcastle United.
Spectacular strikes from Stephane Sessegnon, Adam Johnson and David Vaughan saw the Black Cats to three much-needed points at St James' Park.
Victory on Tyneside was Di Canio's first as Sunderland boss, in his first derby, and he admits he could not have asked for any more from his squad.
He told Sky Sports: "They were warriors. You can't be more proud than this. They did everything, they gave everything, they left all of their energy on the field.
"It was a fair result at 3-0, so I am very happy for them because they really suffered during the game. It was hard because we knew that we had a team in front of us with fantastic ability and quality.
"They worked through the strategy in a perfect way and it was a good result. It was an important result and they deserved it, so I am happy.
"It means that what I thought when I signed, there is quality in this team. There is absolute quality and it is important that we use it in the right way and play together as a team."

Sunderland now sit three points clear of the drop zone, but Di Canio concedes that there is still a lot of hard work to be done if they are to preserve their Premier League status.
He added: "We have to celebrate, but after tonight look to recover our energy.
"We scored three goals, but before we scored the first goal we gave them a chance to score. We have to avoid that. That has to be the philosophy for now until the end of the season and for the future.
"This is only one result. In terms of the result for this area, it is an incredible step. But in terms of the table, it is only a small step to try and get this club out of the relegation zone. We have to be intelligent because the main job is not done."
The Dutchman landed awkwardly after punching away an Adam Johnson free-kick and was immediately replaced by Rob Elliot in the second half of the Magpies' humiliating defeat to their bitter rivals.
And Newcastle's afternoon took another turn for the worse when Pardew revealed he would be deprived of Krul's services for the Premier League run-in.
Although they lie 13th in the table, Newcastle are still looking over their shoulders as they are just five points clear of the drop zone with five games of the season remaining.
They were knocked out of the Europa League by Benfica earlier this week and Pardew must rally his troops without his number one goalkeeper.
It is not the first time Krul, who recently returned to action after missing a month due to an ankle injury, has had problems with his shoulder.
The 25-year-old suffered a similar injury when he was on loan at Falkirk in January 2008.
