Inter Milan defender Jonathan was delighted with victory over Genoa.
The Brazilian is happy playing in coach Walter Mazzarri's system.
"I feel I'm at 70-80 per cent," he said. "Personally I have to continue to make progress.
"Tactically I can improve, although I've already learned a lot. But I want to keep working to do even better.
"The Coach's confidence in me has been crucial and it's something very important for a player. His words encourage me to do well and help me a lot."
