I don't think he "improved". All i think happened was that he was finally given a chance at a club who want him as their star striker. We know ballotelli is impressive. he seems a little more humble now or appreciative of the chance nice gave him. His bowing down celebration showed a lot of respect and was classy.
What is your opinion on ballo? some say he improved, some say he didn't, and some say he should go to hell. What do you think?
