AC Milan striker Pato determined to be fit for derby
Inter are just two points behind the League leaders and can overtake their rivals with a win.
Interviewed by Vanity Fair, Pato said: "I still have a little problem with the left ankle, but I think and I want it to be in place for the derby.
"It's too important," he added. "Last year was a bad year from an injuries point of view. But now, thanks to God, it's all in place."
