Davies enjoyed a successful 2009–10 preseason for Derby, scoring four goals in as many games, prompting manager Nigel Clough to challenge to maintain the form and claim a first team spot heading into the new season. Despite starting in the first team, a succession of injuries meant that Davies only played in two matches between the end of August 2009 and January 2010. After returning to the side in a 1–1 draw away to Millwall in the FA Cup third round on 2 January 2010, Davies embarked on a run of five consecutive appearances, though four were as substitute, his best run of matches since March 2009, and netted twice – the equaliser in the Third Round replay against Millwall and a penalty in a 3–0 win at Peterborough United. Following this run, however, his fitness problems returned and he made four starts in the next seventeen fixtures and, after a late substitute appearance against Crystal Palace in the penultimate home fixture of the campaign, the club announced Davies was to undergo ankle surgery which ruled him out until 1 June. Davies finished the season with just 8 starts and 13 substitute appearances from Derby's 51 league and cup game programme, scoring twice.
