There will be no split loyalties when Ryan Williams comes up against his former colleagues this evening.
The Australian winger made 88 appearances in two seasons with Rotherham before returning to the south coast last summer.
It was an eventful period in his career to date, with promotion to the Championship followed by a drop back into League One.
And while he now focused in helping the Blues achieve success, Williams looks back affectionately at his time with the Millers.
He said: “I’ve exchanged some messages with different people there and I’m really looking forward to it.
“There are only fond memories of my time with Rotherham and I still keep in contact with a few of the guys.
“We obviously got relegated last season, which wasn’t a positive experience, but we still gave a good account of ourselves.
"I’ve got a lot of friends up there, my missus is from Yorkshire and my son was born there as well."
“The main reason I left was because I felt like I needed a fresh start. I wanted to try something new, but it was a hard decision.
“I’ve got a lot of friends up there, my missus is from Yorkshire and my son was born there as well. It’s a place I’m still very fond of.
“But I’m settled down here again now, am enjoying my football and concentrating on helping Pompey do well.
"There are still some old faces from when I was here the last time and those relationships have picked up from where we left off.”
Pompey have plenty of home fixtures during the rest of 2019 and Williams hopes they can make the most of that.
He said: “We’ve got a lot of games coming up against sides above us in the table, so we need to take advantage with the form we’re on.
“The matches add up quickly during these winter months and if you go on a good run, you can make up plenty of ground.
“But we’re not getting too far ahead of ourselves at the moment and just look to win the next one that comes along.”
