Andy Cannon is looking to help Pompey finish the job of securing promotion from League One.
The first signing of the January transfer window has arrived from Rochdale on a two-and-a-half-year deal for an undisclosed fee.
He joins a side sitting five points clear at the top of the table with more than half the campaign played.
And Cannon is excited about the opportunity to make his mark on the Blues’ quest to secure Championship football.
The midfielder said: “This is a massive club and to be able to sign here was an opportunity I couldn’t really turn down.
“My agent rang to tell me about the move and as soon as I heard, I was buzzing. I was over the moon to come down and put pen to paper.
“I’ve played at Fratton Park before and remember thinking ‘wow’ about the noise from the fans when their team scored.
“You want to be competing high up the table and now I want to help this club win promotion and get to the Championship.
"I’ve played at Fratton Park before and remember thinking ‘wow’ about the noise from the fans."
“I spoke to the manager and he made me feel settled straight away. He’s taken charge of big clubs and it’s a compliment that he wants me as his player.”
Cannon featured in both of Rochdale’s defeats to the Blues this term, although he is still smarting about their FA Cup exit last month.
The 22-year-old said: “I’ve come up against Pompey and know they’re a good team, so I can’t wait to play alongside the guys here.
“I think it was a foul on me in the FA Cup game and I should have won a penalty, but the referee didn’t give it!
“We were obviously annoyed about that at the time because we felt that we deserved to have a replay.”
