Saint-Etienne and Gabon striker Pierre Aubameyang has said that he is confident ahead of the nation's final two Olympics Group B matches against Mexico and South Korea.

Aubameyang scored Gabon's equaliser in their 1-1 draw with Switzerland on Thursday and the 23-year-old said that he and his teammates will be able to gradually fulfil their potential in the next group games.

"I'm a bit disappointed because I had two clear-cut chances before scoring the equaliser," Aubameyang told FIFA.com. "I know I've got to iron these things out and be a better finisher. We also had the chance to capitalise when they were reduced to ten men.

"We've got a lot of potential and we're gradually becoming aware of that. It takes a while to get things rolling. I'm feeling pretty optimistic ahead of our second and third matches."

Aubameyang has 25 full international caps for Gabon.
