The two coaches share a relationship that stretches back more than two decades, having first worked together with South Africa national football team in 2000 when De Sa served as goalkeeping coach during Queiroz's stint in charge of the national team.
They reunited again in 2021 after Queiroz was appointed head coach of Egypt national football team, while De Sa also formed part of the backroom staff for Iran national football team at the 2022 FIFA World Cup.
Now part of the Ghana national football team set up ahead of the 2026 global showpiece, De Sa admitted the opportunity was too big to turn down - even if the call came in the early hours of the morning.
"The call from Carlos did not surprise me. We have similar dreams and I always want to see him succeed," De Sa told Beyond The Whistle, as quoted by Allfricafootball.com.
"Being called to assist Carlos was not difficult. This is Ghana and it's the World Cup we are talking about.
"It was an exciting 3am call. I told my wife first and, as custom, she said, 'We are leaving.' I replied, 'Let's go!'"
De Sa also praised Queiroz's management style, highlighting the veteran tactician's openness to different ideas and opinions within the coaching setup.
"Carlos listens. He doesn't have to take every opinion, but he welcomes different views," he said.
The 61-year-old further expressed admiration for the quality within Ghanaian football, insisting the Black Stars possess enough talent to make a strong impression at the tournament in the United States, Canada and Mexico.
"There is so much natural talent in Ghana despite limited resources. As an African football lover, the talent here is unbelievable. You guys don't know what you have with limited facilities and infrastructure," he added.
"We are not going to teach them how to play. We have the players. We only have to put them in the right position, with the right frame of mind, and when they put on the jersey, they should perform."
