Paul Lambert was delighted after watching his Aston Villa side record their first win of the season thanks to goals from newcomers Matthew Lowton and Christian Benteke.
Right-back Lowton broke the deadlock with a 20-yard first-half volley from the edge of the box.
And substitute Benteke wrapped up the points with two minutes left after being put clean through thanks in large to a poor back header from Swansea defender Ashley Williams.
"I thought it was an exceptional performance," Lambert told Sky Sports. "I thought we were absolutely brilliant from the off and I thought we thoroughly deserved to win the game.
"I know people's euphoria, with a new manager coming in, but it'll take time and this is just the start we wanted so we've done great.
"The young lads have done really well against an experienced Swansea side, but on the day I thought we were worthy of the result."
The Scot was also pleased with the display of full-back Lowton and £7million striker Benteke.
"It was one terrific strike with the left boot and I thought his general game on the day was brilliant for us and for somebody who came from League One, he ain't done bad for us.
"Christian is a young lad. He's only 21, so people should not put so much emphasis on his performances. I thought he was unplayable at times when he came on."
