It was Sporting’s first win of the 2026/27 NPFL season and their first league goal since returning to the top flight.
Sodiq Ayoade scored in the seventh minute, the first goal in a Lagos derby for 3,725 days. Aliyu Baba and Valentine Ogwu added second-half goals.
Inter Lagos have now lost all three of their opening fixtures, including two at home. They sit bottom of the table with no points and a -5 goal difference.
Sporting climb to three points from two games. Doma United remain top after beating Enyimba 2-0 on Saturday.
