Petravicius and Newell were signed with a view to the future (but on one year deals weirdly enough) so although neither have had an impact, not a lot was expected. I think there were some injuries in there too.
Plummer was signed to compete for a place in the first team and hasnt done so when there were opportunities to get in the side.
Fisher was Robbos first signing, and it was probably on the back of his goals against us, but hasnt looked like any kind of finisher in his half season. He may not have had a run of first team games, but Im sure that if he was showing great promise in training wed persevere. One thing in his favour is that I dont think we expected to still have moult at the start of the season, nor did we expect bowman to find form, so that probably hit his form/confidence and he hasnt recovered.
I think most of us were positive when we signed him, and I wouldnt put him on the Paul Keegan/John hendry level of terrible strikers, and seems a nice guy, so good luck to him.
