Sharks have intensified their preparation for the new season with the addition of former Shooting Stars coach Festus Allen, who has replaced Abdu Maikaba as assistant coach.
Maikaba has taken over at newly-promoted Wikki Tourists.
According to a statement signed by Sharks spokesman Peter Abaje, Allen is expected to bring his wealth of experience to bear on the Port Harcourt club.
Festus Allen was in charge of ABS FC when they featured in the Nigeria top flight.
Sharks, who placed 13th on the table last season, are currently training in Ijebu-Ode ahead of the new campaign scheduled to begin in March.
