During the 2018–19 season, Hamburg spent most of the first half of the season atop the 2. Bundesliga table, before a dip in form caused the team to finish fourth in the league table, missing out at a chance of promotion. Pierre-Michel Lasogga lead Hamburg in goals during the campaign scoring 19 goals across all competitions.
