Liverpool beat Watford 3-0 at Vicarage Road on Saturday, however they were missing Gomez in defence after the youngster picked up an ankle injury in training ahead of the game.
They face Paris Saint-Germain in France on Wednesday for a pivotal Champions League clash and Klopp confirmed that Gomez will be fit to play.
"I would say 100 per cent," Klopp told Sky Sports when asked if Gomez would be back against PSG.
"He got injured in the last second of the session yesterday - you couldn't believe that but it was like this.
"He could have played probably but if you have the options like we have then you don't take any risks.
"He will be ready for Wednesday, I am sure."
The Reds can qualify should they beat PSG, however any other result will mean they need to beat Napoli at home on match-day six to qualify to the knock-out stages.
