The Mariners have already roped in Eze Kingsley Obumneme and attacking midfielder Ansumana Kromah for the next season.
Dicka was the top scorer in last edition’s I-League as he netted 11 goals in 17 matches for Shillong Lajong. He plied his trade for DSK Shivajians in the 2015-16 season and scored seven from 13 games.
He would play for Mohammedan Sporting in the Calcutta Football League (CFL) and would join Bagan before the I-League commences.
Meanwhile, Bagan have also managed to retain the services of centre-back Kinshuk Debnath.
