The former Wigan Athletic winger completed his move to the Hawthorns yesterday.
"I spoke to a few of the lads: Scott, Liam and Marco only had good things to say. I know Leon (Barnett) was here too, although I didn't speak to him on the move.
"Another person I spoke to was Jason Koumas.
"He said some really nice things about the club - said he loved his time here, loved the fans. He really encouraged me to go for it and said it would be a good move for me.
"We go back a long way from when he was at Wigan about eight years ago. I know he's highly thought of down here by the fans so those comments meant a lot."
Koumas spent five years at Albion between 2002 and 2007, scoring 23 times in 123 appearances.
