Khairul Amri (Tampines Rovers) and Sufian Anuar (Warriors) were signed to booster the depleted squad while midfielder Isa Halim was appointed the new LionsXII captain.

The Football Association of Singapore (FAS) announced a 24-man squad for the new season in December 2013; eight senior players were included in the initial list.

Afiq Yunos' first goal and late winner over ATM saw LionsXII move into the top half of the table for the first time this season.

Two defensive lapses, the second resulting from a wrong judgmental call by Isa Halim in the last minute of regulation time, condemned them to a loss to Kelantan and a first league defeat at home in 19 months.

LionsXII started with Safuwan Baharudin in a supporting role behind striker Khairul Amri against Sarawak a week later; however they succumbed to a second consecutive defeat.

They arrested the slide with a home win over PKNS on 22 March, with Zulfahmi Arifin scoring with a free kick on his return to the first XI and Faris Ramli with the winner on the hour mark.

This marked the last game before captain Isa was ruled out for the rest of the league campaign following surgery on his persistent Achilles' tendon injury.

LionsXII finally ended the three-match losing streak by edging relegation-threatened ATM in a 2–1 victory, concluding the rounds of fixtures in May.
