Bobby made a heck of a difference to our midfield when we signed him from Palace (I think). I know I'm looking at things through rose-coloured specs but just look at the quality of midfielders we had in that era: Gibson, Woodruff, Leslie Lea, not to mention Malcolm Clarke, Spider and out wide Peter King and Barrie Jones. And later on Johnny Vincent, Doug Livermore, etc.

Even one decent playmaker would improve the current side immeasurably but for whatever reason the management don't consider it a priority.
Lee Tomlin is the nearest we have but with his fitness level and injury concerns he can't be relied upon.
