Following his team's 3-2 loss to Portugal in their World Cup opener on Thursday, Ghana head coach Otto Addo criticized the Cristiano Ronaldo penalty decision.

In the second half, Mohammed Salisu fouled Ronaldo, who then stepped up to convert the penalty. With this goal, Ronaldo became the first male player to score in five different tournaments and cemented his place in World Cup history.

Osman Bukari's goal for Ghana in the 89th minute gave Portugal a scare, but they were unable to score an equalizer in stoppage time.

After the match, American referee Ismail Elfath came under fire from Addo for giving Portugal a penalty.

"The referee gave a penalty that was not a penalty – everyone saw that." Why? Because it’s Ronaldo or something? Addo said to beIN Sport.

When asked in his post-match press conference if he believes the foul was given because it was Ronaldo, Addo replied: "I think you have to ask the referee." I have no proof of that. We were playing the ball, and then there was contact.

I don’t know whether they were not paying attention or whether the VAR was not paying attention.

If you look at the replay, we played the ball; it was actually a foul against us.

"If somebody scores a goal, congratulations." But this was really a gift.

"Up to the penalty, everything was possible." Then the game got a little bit wild.’
