The Catalan giants will now be looking to return to winning ways in the league ahead of their home game against the reigning champions Real Madrid on October 24.
Here, Sports Mole looks at how Barca could line up against a Getafe side that have picked up seven points from their first four league matches of the campaign.
Koeman will have to assess the fitness of his players ahead of this match as a number have been on international duty and might only train once before Saturday's contest in the capital.
Marc-Andre ter Stegen's ongoing absence with a knee injury means that Neto will continue between the sticks, while Jordi Alba is definitely on the sidelines with a hamstring issue.
Junior Firpo is also a doubt with a hamstring problem, meaning that summer arrival Sergino Dest could make his full debut for the Catalan giants from the left-back position.
There was some initial concern when Miralem Pjanic was replaced during Bosnia-Herzegovina's clash with Poland on Wednesday, but the experienced midfielder is said to be fit for this match and could be handed a starting role with Philippe Coutinho potentially rested ahead of El Clasico.
