Huntelaar has been struggling to make his mark with Leonardo's side since signing from Real Madrid in the summer, but Pato called for patience on his colleague.

"When I first came it wasn't easy since I didn't speak the language properly. I was worried about making errors," said Pato.

"Maybe Klaas-Jan Huntelaar is suffering the same kind of problems. But I am confident he will be very important for us."

The Brazilian ace, who is Milan's top scorer in the Serie A, paid tribute compatriot Leonardo.

"I feel really calm and confident because Leonardo gave me serenity" Pato added.

"I do not feel the pressure and this is fundamental for me. I have also learnt a lot."
