He performed a vital role in Burton’s ascent up the Football League.
But Tom Naylor did not have to think twice about becoming the latest addition to Kenny Jackett’s squad.
The midfielder turned down offers of a new deal with the recently-relegated Brewers to pen a three-year contract with Pompey.
And having played second tier football last term, Naylor is confident that he can return there with the Blues.
He said: “It’s a massive move and as soon as I heard of Pompey’s interest, I wanted to speak to them as soon as possible.
"This is a huge club and I think that we’ve got a chance of going up."
“I’ve had some good times at Burton – winning back-to-back promotions and staying up in our first year in the Championship.
“But this is a huge club and I think that we’ve got a chance of going up and then you never know what can happen.
“I’m going to first focus on pre-season and then League One, so I’m really looking forward to meeting the lads and getting started.
“I like to sit in that holding role and try to break things up, get the ball down and play – and also get the odd goal as well.”
Naylor has not featured at Fratton Park since he was on loan at Newport when the Welsh side secured a 2-0 victory back in 2013.
He said: “It was a few years ago, but the atmosphere really stands out because the fans were bouncing from the first whistle until the last.
“I’m looking forward to experiencing that every week and I’m sure it will be a nice feeling walking out on to the pitch.”
