Kwesi Appiah's outfit, who have made the semi-final of the last six championships and the final in 2010 and 2015, are in the hunt for their first title in 37 years.
The last of their four continental successes came in 1982.
“Automatically we have to be under pressure because for the past three Afcons, we always make it to the semi-final but yet we don’t win it," Deportivo Alaves ace Wakaso said, as reported by Footballmadeinghana.
“We always had it in mind to come back with the trophy but it hasn’t happened.
“I think [in my opinion] as a player, we need to sit down and put things in order before we move to this particular tournament.
“The problem remains how we will manage ourselves outside the pitch before we go on to play."
Together with Cameroon, Benin and Guinea-Bissau, Ghana are in Group F for the June 21-July 19 tournament.
The Black Stars will open their campaign against Benin on June 25 and face Cameroon and Guinea-Bissau on June 29 and July 2 respectively.
