The striker followed up his effort in the win over Genoa with a brace last night in Holland.
"I am so happy. I really needed these goals, I couldn't wait to get back on the scoresheet and I thank God for all of this," said Amauri.
"Now I hope to continue along this path, because it is very important for me.
"I had a slight sciatica problem on Sunday and tonight. It is a little inflamed, but nothing to worry about."
It is no coincidence that Juve rediscovered their winning streak once Amauri ended his drought.
"My improvement is really that of the whole team and I am happy about that," he insisted.
"As for my goals, when a good ball comes in then it's easier to score. Tonight two great crosses arrived and thankfully I got them in the back of the net."
