Pato has impressed this season with 15 goals in all competitions.
“They try not to let me play quickly, but I don’t just get the ball anymore. Now everyone aims straight at my legs,” Pato told Milan Channel.
“I don’t know what more they have to do for me to get a free kick. It becomes difficult to play in these circumstances.
“Having said that, it is easy to score goals at Milan, as there are so many great players who put you in the best position to net. I also get to ‘steal’ secrets from giants like [Pippo] Inzaghi and [Andriy] Shevchenko, so I am incredibly lucky.”
