James Vaughan helped Wigan secure promotion to the Championship last term.
Now he is looking to make it two successful League One seasons in succession after arriving on the south coast.
The striker has joined Pompey from the Latics in a loan deal that runs until the end of the current campaign.
And with the Blues currently sitting second in the table, he is eager to help them get over the line.
Vaughan said: “It’s been a bit of a whirlwind 24 hours for me, but as son as I got the call, it was something I had my eye on.
“There were a few lads at Wigan who used to be here and every one of them had good words to say about Pompey.
"I had the feeling of getting promoted last season and it’s something that I’d like to replicate this time around."
“I’ve played down here before and know all about the atmosphere, while the club are doing really well and I want to be part of a promotion push.
“The manager explained how we were going to play and what he expected of me – it seemed like a great match.
“I had the feeling of getting promoted last season and it’s something that I’d like to replicate this time around.
“This is definitely a club that should be at a higher level, but everyone here knows we’re on the road back to where we need to be.
“Goals are what strikers are judged on and it’s what we love doing – hopefully I can contribute a few to help the team.”
When Vaughan found the net for Everton against Crystal Palace in 2005 he became the Premier League’s youngest scorer at 16 years and 271 days – a record that still stands today.
“It feels like a long time ago now,” he said. “But it was a dream come true for me. I look back and it’s something I’m really proud of.”
