Manager Dean Holdsworth believes Risser will give his side great impetus going forward and also Holdsworth also spoke of Risser's experience.Wilko gives us something different for our strikers to play-off. When I made a phone call to his agent within 20 minutes Wilko was on a plane and made himself available. Currently he is on a short-term contract but he could become a good asset for us. He is well travelled and he wants to prove a few things to people and we can take advantage of that.
The day after signing for the club, He made his debut on 14 February 2012 in a 1–0 home win against Hereford United. 4 Days later on 18 February 2012, Risser provided an assist for Aaron Morris to score on a 65th minutes which turns out to be a winner against Macclesfield Town.
