new Derby manager Steve McClaren, Martin scored the first goal, which was also his 50th career league goal, as Derby beat Leeds United 3–1, recording their 10th consecutive win against their fierce rivals. His fifth league goal of the season was the last in a 3–0 win over Sheffield Wednesday on 9 November. He then scored five goals in three games: one each in 3–1 and 2–1 wins against Wigan Athletic and Middlesbrough on 1 and 4 December, respectively, and then his first ever league hat-trick in a 5–1 win against Blackpool on 7 December. On 29 December, Martin scored a brace against Barnsley to help Derby win 2–1. This took his goal tally for the season up to 15 in all competitions. After going five league and cup games without scoring, his longest goal drought of the season, Martin scored in the 95th minute in Derby's home match against Yeovil Town on 28 January 2014 to win the game 3–2. Martin scored in the Championship play-off semi final 1st leg against Brighton and Hove Albion from a penalty, he also forced Brighton's keeper Tomas Kuszczak into scoring an own goal. 2014–15 season Martin had a relatively slow start to the season: he scored once in a 2–0 League Cup win against Carlisle United on 11 August 2014, twice in a 5–1 win at home to Fulham on 23 August and once in a 1–1 draw against Ipswich Town on 30 August; these the only goals he scored in the first eleven league and cup matches of the season. He then scored three goals in four days: both goals in a 2–0 win at Bolton Wanderers on 27 September and the second in a 2–0 win at home to AFC Bournemouth on 30 September. Another two goals followed in a 3–0 win at Reading on 18 October, an 81st-minute penalty in a 1–0 win against Blackpool on 21 October, then another penalty against Fulham in a 5–2 League Cup win, before scoring the opening goal in a 2–1 defeat to Brentford on 1 November. After four matches without a goal, Martin scored another brace, his fourth of the season and seventh for Derby, in a 3–0 win against Brighton on 6 December. His fifteenth and sixteenth goals of the season came in a 2–2 draw against Norwich City on 20 December and in a 4–0 win against Birmingham City on
