The 34-year-old midfielder made more than 150 appearances for Albion after joining in March 2009 from Stockport County. He made the move permanent in July 2009 and spent the next four seasons with the club.

After spells with Rochdale, Crawley Town and Carlisle, Dicker joined Scottish Premiership side Kilmarnock in 2016, making more than 150 appearances and coaching the reserve team for four years before he was released at the end of last season.

Dicker's role with the under-23s will be similar to that of his former Albion teammate Andrew Crofts, who mentored and coached the young players before he was appointed under-23s head coach.
