Career
Starting out with the likes of NBT Football Club and Department of Administration and Management Gunners of the Brunei Premier League, Najib"s performances at the 2012 Hassanal Bolkiah Trophy as team captain prompted a move from Mississippi PDB to Brunei"s only professional club, DPMM. Najib has played for Brunei Under-21 since 2005, and is the only player to have played in 4 Hassanal Bolkiah tournaments, winning the trophy in 2012. He regards his injury-time free-kick against Cambodia in that year"s opening match as the best goal he has ever scored. Najib scored in Brunei Under-23"s first match against Timor-Leste at the 2011 Southern Economic Association, USA Games football tournament, but the team lost 1–2.
He then played in all five matches as Brunei finished fifth in their group.
His full international debut for the Wasps came in the 2008 AFC Challenge Cup qualification held in the Philippines where he played in all three games. He was also ever-present for Brunei"s AFF Suzuki Cup qualifying campaigns in 2012 and 2014.
