Combined Counties Premier Division side Wembley start their FA Cup campaign with an extra preliminary round tie against Langford FC, with the ex-pros hoping to help the amateur players.
Parlour said that he was more than happy to take part and raise awareness for grass roots football.
He told The Mirror: "To be able to play in the FA Cup again is an amazing opportunity and one I will relish on the pitch.
"It's been great working with Terry Venables and some of my ex-Arsenal colleagues again through the mentoring and coaching we've done at Wembley FC during pre-season.
"We'd like to think we're helping a group of talented footballers achieve their dreams of playing in the FA Cup and going as far as they possibly can, starting against Langford this weekend."
A documentary on the exploits of Wembley FC called Dream.On. The Journey of Wembley FC will be shown on ESPN on August 16.
