Pato delighted with AC Milan return
Pato had been out of action since suffering yet another thigh strain at the end of September and was unfortunate not to score in Saturday night's 0-0 draw with Fiorentina, hitting the post.
"I could've played sooner, but I trained so hard and I missed the pitch during these two months," said The Duck.
"It felt great, as I was able to make my usual movements. I was a bit unlucky with the upright, but hopefully the ball will go in easier on Wednesday against Barcelona."
