Can Gills get back to winning ways by overcoming a strong Pompey side at ME7?
Steve Evans will be hoping his side can bounce back from Saturday's defeat at MK Dons by overcoming a strong Portsmouth side at MEMS Priestfield Stadium on Tuesday evening.
Both the manager and assistant manager have called for their players to put in a response, but they will need to be "at their best" to record all three points against Pompey who are one of the favourites to gain promotion this season.
