The club then began the month of December with a home match against United on 1 December 2013. After taking the lead in the 77th minute through academy product Nikhil Kadam, United scored their equalizer seven minutes later to force Pune to begin the month with a 1–1 draw. The month then did not get better for Pune as they succumbed to their second defeat of the season at home to arch-rivals Mumbai on 7 December 2013. After going down early to a goal from former India international Pappachen Pradeep, Pune equalized through current India international Arata Izumi in the 41st minute. However, Mumbai scored the winning goal in the 60th minute through Yusif Yakubu. The club then fell to their second defeat in a row in their next match against Rangdajied United at the Nehru Stadium in which, after taking a halftime 2–0 lead through Riga Mustapha and Gurjinder Kumar, the club gave away three second half goals (including two in stoppage time) to lose 3–2. However the club then returned to winning ways when they faced United for the second time that month at the Kalyani Stadium on 15 December 2013. An early brace from Riga Mustapha helped Pune to a 2–1 victory. But that was only a short-lived moment for the club as the side quickly fell to third loss of the season in their next match against Mohun Bagan on 21 December 2013. A brace from Odafe Onyeka Okolie and a goal from Ram Malik saw Pune lose 3–1 with the only Pune goal coming from Academy product Thongkhosiem Haokip.
