AC Milan boss Max Allegri isn't concerned over their stuttering start to 2011.
The Rossoneri have a four-point lead on second place, but have won just one of their last four games.
He said: "We are still first in the table. We have to remain optimistic and keep working."
Asked about Alexandre Pato's compatibility with Zlatan Ibrahimovic, he said: "Tomorrow's Coppa Italia match against Bari is not a test for him, but rather an important challenge for us.
"We want to go through to the next round and to win to continue our progress in the Coppa Italia.
"It's an objective we all believe in and one that we want to realise."
