The Black Stars lost by three first half goals - in a 45 minutes that was largely dominated by the Brazilians.
In the post-match presser, he defended his starting 11 and stressed that decisions going forward will be based on performances.
"My selection was not a gamble. It was a decision of complex things. Line up was good but we had to work harder to close the spaces.
"I think I made mistakes, I learnt a lot more about my players, and picking the next 11 will depend on the performance in the next game," he stressed.
