Marcus Harness admitted that the chance to join Pompey was an invitation that proved impossible to decline.
The winger has become the latest addition to Kenny Jackett’s squad, penning an initial three-year deal with the club.
It ends a long spell with fellow League One outfit Burton that began when the 23-year-old was just a teenager.
And now he is focused on trying to help secure Championship football for his new club following last season’s near miss.
Harness said: “I’ve been at Burton since I was 14 and now it’s nice to move on to the next step in my career.
“I loved my time there, but sometimes you get opportunities that you just can’t turn down – I’ve played at Fratton Park before and know the size of this club.
“The fans here are amazing and I remember watching them in the Premier League when I was younger, so this felt like a chance to progress.
"I loved my time there, but sometimes you get opportunities that you just can’t turn down."
“I’d heard murmurs for a few weeks and then things happened literally overnight. It’s all gone so fast.
“It’s been a bit mad for me, but I’m just happy to be here and am really excited about what’s to come.
“I try to create and score goals. I want to get on the ball and make things happen – hopefully I can do a lot of that here.
“The gaffer thinks I can fit in to what he’s trying to do that, so I want to get into the team and help them to push on.
“I know this club should be higher than they currently are and will be working hard with the rest of the lads to make that happen.”

Harness produced an impressive display for Burton when they suffered a last-gasp defeat to Pompey back in April.
He said: “It was a good game for me and an enjoyable one to play in – even if you guys snatched it right at the end!
“We were gutted by the result, although I’m not sure we had much to play for at that stage of the season.”
