Morale is high at Scunthorpe after their 2-2 draw secured through a last minute goal at in form Yeovil on Tuesday. The Lincolnshire side have said that it felt like a win after the Glovers had declared beforehand that it was their cup final.
The view being taken is that the Addicks are there for the taking after their two recent shock defeats, giving a further boost to Scunthorpe's battle against relegation.
At the beginning of the season Scunthorpe were seen as potential promotion candidates rather than likely to be involved in a battle to escape relegation.
Scunthorpe are the draw specialists of the division, having shared the points in no less than sixteen games this season. At home they have won four, drawn seven and lost seven. It could be another draw on Saturday.
