The La Liga champions started the new campaign with a 0-0 stalemate against Real Sociedad, although the Belgian shot-stopper is still confident that his team can do damage at the other end of the pitch.
He told Movistar: "Of course we've got goals. You see it in training, you see it in the last pre-season friendly we had against Getafe [a 6-0 win].
"But sometimes the ball just doesn't want to go in. I don't have any doubt there are plenty of goals in this team."
Madrid have let attackers Gareth Bale and James Rodriguez leave this summer, while Eden Hazard missed the match due to injury although Courtois is confident that Karim Benzema can replicate his form from last season.
The former Chelsea goalkeeper said: "If we don't concede too many goals and we can order ourselves and be difficult to score against, we have at the other end of the pitch Karim Benzema, who always plays at a very high level and didn't have any luck tonight.
"It's always important for us to keep a clean sheet. That's the way it went after lockdown. It ended up that many of our games were without conceding."
Martin Odegaard made his full league debut for Madrid against his former club and described it a "special night".
He said: "It was a very special game for me. I was playing against friends, good people. Very special.
"I felt good, but obviously the victory was missing."
