The forward has apologized for his act of gamesmanship in his side's Champions League encounter and promised the incident will never happen again.
With 24 minutes gone, Morten Nordstrand received treatment for an injury, but with the ball passed back to the hosts' goalkeeper as an act of fair play, the ball was intercepted by Adriano who proceeded to burst through the watching defense, round the keeper and fire home.
"I did not see the start of the move, because I was standing with my back to the ball and my face towards the opposition goal," Adriano told the club's website. "I was in the attacking area and did not notice what had happened in our half. I was very focused on the game, and when the ball dropped near me the defenders did not show any initiative. I picked up the ball, beat the goalkeeper and scored - I am a forward, that is what I do.
"Later, after analyzing the replay of that episode and after talking to my teammates, I realized what had happened and I completely changed my view on the episode. I am very sorry about what happened, I apologize to all the fans and to UEFA."
The Brazilian has since been vilified in numerous quarters for his actions but has promised the incident will never be repeated.
"Nothing like this ever happened to me before, I have always respected and will respect the Fair Play rules," he continued. "Once again, I apologize and I promise that this will never happen again. I will be more focused and attentive on the pitch and I will abide by the rules of fair play."
Adriano went on to score another two goals as Shakhtar ran out as 5-2 winners.
