Antwi was between the sticks for the Black Stars in their international friendly encounter against Namibia which they lost 4-1 on penalties after playing 1-1 in regulation time.
The former Asante Kotoko custodian believes he can become the Stars number one goalkeeper if given the opportunity.
"Always am ready to help my country when invited to camp"I feel happy being chosen to manage the goal post, is not eazy to get that opportunity,” Antwi told FootballGhana.com
"It's a chance I have being waiting as a Ghanaian and should I have it each time, will do my best".
He added, “It needs extra hardwork to maintain the post because all the goalkeepers there are very good and competitors as well.”
