Ledley scored in the first match of the 2006–07 season, the opener in a 2–1 win over Barnsley. He then scored several weeks later, as Cardiff City beat fellow promotion contenders Birmingham City, 2–0, to move top of the table. At this match Cardiff City had a full stadium, 20,000 fans, for the first time in over 45 years. This signalled their growing momentum in the league and the belief within the club that they were able to get promoted. Ledley was identified as one of the key players in Cardiff City's team, his pace on the left wing being vital to their tenacious style of play. On 25 September, Ledley scored in a 3–0 win over Southend United to confirm Cardiff's status as early season favourites. Cardiff entered the FA Cup at the third round and drew Tottenham Hotspur. The match ended 0–0 but Ledley had an excellent chance to put Cardiff City in the lead after 55 minutes, he got on the end of a cross but hit his shot just over the bar. The match went to a replay and Tottenham Hotspur won 4–0 at White Hart Lane on 17 January. On 2 February Ledley suffered a hamstring injury in a 2–0 win over Barnsley. At the end of the season he picked up the Football League goal of the season award for his strike against Barnsley.
