Championship Middlesbrough played hosts to Charlton Athletic on Saturday, and many would of missed the first goal still paying for their hot dog as Bradley Pritchard slammed home the opener in the first minute for the visitors.
An own-goal doubled the visitors lead, and Powell admitted he was delighted by the quick start his side made at the Riverside.
He told the official Charlton website: “We started off at a great pace and I thought our first half display was one of the best, if not our best, exhibition of football. It was outstanding.”
After the break, Boro striker Marvin Emnes screwed a glorious chance wide, but later made amends when he scuffed home past stopper Ben Hamer to close the gap.
Ricardo Fuller at the other end tapped in, only to be denied a goal which would've made the score 3-1 by the linesman's flag.
Powell continued: “Certain incidents were missed. Ricardo Fuller scores a perfectly good goal which was adjudged offside but was clearly on. He got fouled which was a clear-cut pen."
Powell was left slightly annoyed as Aussie forward Scott McDonald then scored with his head to earn Tony Mowbray's team a draw with minutes remaining.
On the Middlesbrough official website, Mowbray apologised to the Boro faithful after their frustrating end to the campaign.
"I'm a Boro fan and have been since the age of six and I understand their frustration. We built an expectation in the first half of the season and let people down by not maintaining it," he said.
Charlton will narrowly miss out the play-offs, but will be happy to secure their Championship status for next season after an impressive recent run.
