Ghana coach Otto Addo feels disappointed with his team's vulnerability from set-piece situations in a 3-0 loss to Brazil.
Brazil, the world's top-ranked side, tore Ghana apart in a dominant first half in Le Havre, with Richarlison striking twice after Marquinhos headed in the opener from a corner.
The second of Richarlison's goals came from a Neymar free-kick, with the Tottenham Hotspur forward nodding in at the near post.
Addo admitted to being "very unhappy" with the nature of his team's defending at set-pieces, but insisted the loss to Brazil would provide a useful learning opportunity before heading to Qatar.
"In all, the team was bad, if you lose 3-0 you're bad," Addo said after Ghana suffered their fifth defeat in as many meetings with Brazil.
"I was very disappointed, especially with the set-pieces. They had a lot of chances. We were a bit lucky in some situations they didn't score."
"If you see how many times they (Brazil) have scored three or four goals, then nobody's ready," said Addo.
"It's not like we were playing against some small boys. They're really, really good."
"We lost 3-0 so everybody probably thinks this is a weak team. This is maybe an advantage for us," he said.
"Everything brings something good if you learn from it. I hope that I learnt myself. Maybe I have to do some things differently. If everybody thinks like that then we'll do better. I'm not concerned at all."
"I made some mistakes, I will learn from them and can hopefully improve," he added
Ghana will play Nicaragua in another international friendly on Tuesday, 27th September, 2022 at the Estadio Francisco Artés Carrasco in Lorch, Spain.
Ghana have been paired with Portugal (November 24), South Korea (November 28) and Uruguay (December 2) in Group H in the 2022 FIFA World Cup.
