Adi began his footballing career with Manggis United, coached by former Brunei forward Majidi Ghani. He joined newly promoted Majra FC in 2007 and played for them in the Brunei Premier League until 2012,[5] when his exploits on the international scene attracted Brunei's sole professional club DPMM FC to sign him for the 2012 S.League season.[6] He scored his first goal for DPMM against Warriors FC on 23 June that year.[7]
Adi saw much playing time as a substitute in the following season, but the squad played underwhelmingly and finished in eighth place, costing Vjeran Simunic his job.[8] Adi's new coach Steve Kean in contrast was more reluctant to utilise him, restricting Adi to only 10 appearances in the 2014 S.League. However, he made most of his chances count, scoring in the final of the League Cup,[9] and netting two braces against Hougang United and Woodlands Wellington in an August purple patch.[10][11]
Adi scored 8 goals in all competitions in a largely disappointing 2017, to finish behind Rafael Ramazotti in the club's goalscoring tally for the year. The following season, Adi started ahead of elder brother and new captain Shahrazen in a new 4-3-3 formation deployed by Brazilian coach Renê Weber.[13] Adi finished the season with 11 goals and 10 assists, making him joint-top assist-maker of the league, the other being Riku Moriyasu of Albirex Niigata (S).[14]
UiTM FC
After a successful trial in December 2018 (including scoring a hat-trick in a friendly), Adi signed a one-year contract with Malaysia Premier League side UiTM FC, becoming the first Bruneian local-born expatriate footballer ever.[15][16] He scored within twenty seconds of his debut in a 1–3 victory against PDRM FA on 1 February, managing to get into the scoresheet twice.[17] After two goals and six assists, he was released by UiTM FC in late May.[18]
Back to DPMM
Two months later, Adi returned to DPMM FC and made his first appearance since coming back in the 3–3 draw against Warriors FC on 6 July.[19] He scored his first goal since his return in the 3–0 victory over Geylang International on 2 August, in a game where his younger brother Hakeme debuted for the first team and shared a scoresheet with.[20] He netted a brace in the penultimate league fixture which was a 5–4 home win against Hougang United on 29 September.[21]
Adi signed for Kasuka FC in time for the 2022 Brunei FA Cup season. He scored a brace on his debut against Lun Bawang FC in a 13–0 victory on 7 August.[25] He followed this with four goals in the next fixture against Dagang FT.[26] He scored a total of 20 goals en route to the final of the competition where he faced off against his former club DPMM FC in a losing effort, 2–1 at the Track & Field Sports Complex on 4 December.[27]
Adi scored the first goal of the 2023 Brunei Super League against MS PPDB on 3 March, which finished 4–0.[28] On 25 June, he scored a hat-trick in an 8–1 win over Jerudong FC.[29] A month later against Wijaya FC, he scored twice in the first half when the match was postponed due to heavy rain seven minutes after the restart. The match resumed on 2 August when he scored a penalty and finished the match 8–1, in doing so became the footballer who achieved the longest hat-trick ever.[30][31][32] At the conclusion of the league, Adi gained his first local championship medal after propelling Kasuka to the league title unbeaten, scoring 23 goals in 15 appearances.[33]
In the first game for Kasuka as defending champions in the 2024–25 season on 1 September 2024, Adi scored a hat-trick against Lun Bawang to help his side gain a 9–0 victory.[34]
International career
Like his brother Shahrazen Said, Adi became an undisputed starter in the forward position for the Brunei national team at various levels.
Adi played a starring role in helping the Brunei under-21s win the 2012 edition of the Hassanal Bolkiah Trophy, a tournament for the national under-21 teams of the ASEAN Football Federation. He scored 5 goals, scoring in every game to become joint top scorer with Indonesia's Andik Vermansyah.[35] In the 2014 tournament, he was picked as one of the 5 permitted overage players and once again became the top scorer with 6 goals, despite being eliminated in the group stage.
Despite his irregular club form, Adi was selected for the 2016 AFF Suzuki Cup qualification matches held in Cambodia in October.[38] He scored the first goal against Timor-Leste in Brunei's first group match, which went 2–1 to the Wasps.[39] He also began the scoring in the third game against Laos but this time Brunei lost 4–3.[40]
Adi was back in the starting lineup for the 2016 AFC Solidarity Cup held a fortnight later in neighbouring Sarawak, Malaysia. He scored from a direct free-kick in the 4–0 win over Timor-Leste.[41] In the semi-final against Macau, he was sacrificed when fielding the replacement goalkeeper after Wardun Yussof was sent off in the 55th minute. Brunei lost 4–3 on penalties in the end.[42]
Adi laced up for the national team at the 2018 AFF Suzuki Cup qualifying matches against Timor-Leste held in early September.[43] Adi made appearances in both legs as Brunei failed to progress to the Suzuki Cup group stages with a 2–3 aggregate score.[44]
Adi was selected for the two-legged 2022 World Cup qualification matches against Mongolia in June 2019.[45] He started the first leg in Ulanbaatar which finished 2–0 to the Blue Wolves.[46] In the second leg, Adi fired in a long-range free-kick which was parried to the path of Razimie Ramlli for Brunei's second goal to level the tie on aggregate.[47] Unfortunately Mongolia subsequently scored a penalty to knock Brunei out of the 2022 World Cup and also the 2023 Asian Cup.[48]
In November 2022, Brunei finally managed to qualify for the 2022 AFF Championship via a 6–3 aggregate win over Timor-Leste in the qualifying round.[49] Adi made two substitute appearances, creating two goals in the first leg.[50] He donned the Brunei jersey a total of three times in the actual tournament, but failed to make an influence as Brunei lost all of their matches in the group stage.[51]
Adi received a call-up for the two-legged 2026 World Cup qualification matches against Indonesia in October 2023.[52] Adi managed two substitute appearances but failed to exert his influence as Brunei were defeated 0–12 on aggregate.[53]
