Sao Paulo are weighing how to punish loan star Adriano after the troubled Brazil international arrived for training late, left early and shoved a cameraman on his way out.

Since arriving from Inter Milan, the power forward has already caused controversy on a few occasions, including a late night one-car accident.

"We're going to analyze the facts to decide whether or not there will be a fine," club director Marco Aurelio Cunha told reporters. "The important thing here is that there is a healthy atmosphere - people have to be happy here and if they are not happy, they don't need to stay."

"This is absolutely wrong and I cannot justify this at all."
