St Joseph's Institution (SJI) ended a 30-year wait for their first football title when they beat Queensway Secondary School 1-0 in the final of the National Schools' South Zone B Division Football Championship on Wednesday.

The goal at Safra Tampines also came in dramatic fashion, as left-winger Jared Ng, 15, was left unmarked in the penalty area to prod home the winner in the second half of extra-time to spark mayhem among the SJI bench.

The boys in green and white, coached by former Singapore national defender Kadir Yahaya, then had to survive the dismissal of striker Mari Martinez as they clung on for a memorable victory.

Once a traditional power in football in the 1960s and 70s, SJI became better known for its rugby teams and took football off its list of co-curricular activities in 2000, citing declining interest and resource constraints.

It eventually reintroduced football into its curriculum in 2012 and hired Kadir, who was also the assistant coach of the LionsXII during their maiden campaign in the Malaysian Super League that same year.
