Phillips' Crystal Palace face the Baggies today.
"I'm looking forward to it," Phillips told the Birmingham Mail.
"I never wanted to leave - as has been well documented - and my two years at West Brom were among the highlights of my career.
"I guess this will be my final time back as a player. I still live in the area, I still have a lot of time for the club and the fans and it'll be nice to say a 'goodbye' to everyone."
