"Tonight I scored two important goals and the team did well. It was a tough game away from home against Palermo and everything went well. I am very happy," said the Inter star.
He scored both goals in Sicily in spectacular fashion with fierce right-foot strikes that left the goalkeeper with no chance.
"I have hit a few powerful free kicks in my career and I'm trying in training to hone my technique. I always work to get better at everything."
The Swede added: "It was a crucial win and we are top of the table, so we must continue this way. The next game against Juve is very difficult, but if we want to win the Scudetto then we need a victory.
"Just a few weeks ago we were a long way off from Juve and now they are just three points behind, so you never can tell in football."
