The 56-years-old trainer has constantly invited fresh faces into the Black Stars set up in a bid to build a formidable squad ahead of the 2019 AFCON in Cameroon.
Ahead of the 2018 World Cup qualifier against the Cranes of Uganda and the international friendly clash against Saudi Arabia, Appiah handed call-ups to six debutants.
And following the team's convincing 3-0 win over 2018 World Cup finalists Saudi Arabia, the former Al Khartoum Watani gaffer was asked if the players at his disposal have solved his experimentation.
"I don't believe it's been solved yet because we still need to be %100 sure about these players. Some players might play one or two games and do well but in the subsequent games they might not be the perfect type that you want and for that reason I always believe in giving players more opportunities to play so that we can all be %100 sure they're the right players to replace whoever is out of the team," Appiah answered.
"The process will keep going on but I've given myself time. By next year or in the middle of next year I'll have to stop inviting so many new players into the team because you see, If you're building a team you don't wait 2019 before you start inviting new players or 2018, and that's the reason all along this year I made my mind to try and invite so many players so that we can all be %100 sure we have some alternatives."
"Now I'm looking by the middle of next year to stop the invitation of mass players and limit it to those that we are %100 sure they can form nucleus of the team in 2019, and then build the team around then and make sure tactically they will understand our vision and our tactical play before 2019. I don't need to wait to the last minute," he deduced.
