Gareth went into the 2008–09 season hoping to help Marsaxlokk gain some more silverware, however the club had an extremely disappointing start to the season by their own high standards, and only managed to gain a place in the championship pool by beating Msida Saint-Joseph in the final game of the first round. Sciberras made 25 appearances, but failed to score any goals during the season. Despite the club's extremely disappointing start to the season, they managed to finish the season in 4th position in the Maltese Premier League.
