Aidy Boothroyd's side lost four of their five league games and saw three players sent off during the month to quickly signal that a relegation battle was on the cards at Sixfields.
Loanee striker Jacob Blyth was a bright spark, scoring twice during the month, but Boothroyd was already being forced to chop and change his side in a bid to find a settled XI.
Chris Wilder's side ended the campaign on a high and the manager has moved quickly to strengthen the squad. His Oxford United side were out of the blocks very quickly in 2013/14, winning 4-1 at Portsmouth on the opening day and taking 11 points from a possible 15.
