Black Stars head coach Otto Addo said he tried speaking with referee Ismail Elfath after their 3-2 defeat to Portugal in their 2022 World Cup opener on Thursday.
The 47-year-old was furious that referee Elfath pointed to the spot in the 63rd minute and argued that Ronaldo had actually fouled Mohammed Salisu.
After the goalless first half, Ronaldo opened the scoring for Portugal via the penalty spot but Ghana improved after the goal and scored the equalised through skipper Andre Ayew from close range.
Portugal responded with two goals in two minutes to seal the points - Joao Felix converting a delightfully clipped finish and substitute Rafael Leao coolly stroking in just seconds after coming on.
Osman Bukari headed in a late consolation for Ghana and there could have been real drama in the ninth minute of stoppage time.
"I tried. I asked some people from FIFA if I could talk briefly to the referee in a calm and quite way. But they said he is in a meeting and so it’s not possible," coach Addo said after the game.
"I think they do match analysis with their instructor after the match so they go through the match. But surely, may be sometimes you could have some minutes for the coach."
The defeat means Black Stars are bottom of Group H after Uruguay and South Korea played out a goalless draw earlier on Thursday.
The Black Stars will now switch their attention to their attention to the match against South Korea on Monday before taking on Uruguay on December 2 at the Education City stadium.
