Michael Jacobs makes emotional Wigan Athletic farewell
Jacobs, the longest-serving first-teamer at the DW Stadium last season, was a free agent after his contract expired in the summer.
And after joining Pompey on a two-year-deal, the Rothwell-born winger said an emotional goodbye to everyone connected to Wigan.
"Latics players, fans and staff..." he wrote. "Just wanted to say it's been a privilege over the past five years representing the football club through the good times and the bad.
"We had two brilliant promotions and, on a personal note, to rack up nearly 200 appearances with 32 goals and 32 assists is something I'll always be proud of.
"I've met a lot of fantastic people along the way, and to see some of them lose their jobs over the last few months is devastating.
"With the help of the supporters and a new owner, I really hope the club makes it through this difficult time.
"Good luck for the season and the future.
"Thanks again! Crackers."
