"The fact we have some problems right now is beyond doubt, because we have drawn our last three home games, but this is due to the fact we keep facing teams with very tight defences," said Ancelotti.
"The trouble is that these systems force you out wide to find space with crosses, but we don't have players who are good in the air when the entire defence is in place. There are problems, but no tension. Our atmosphere has always been relaxed and that was the key to our success last year. It will be the same this season."
He also admitted: "We play a very tiring style of football. Kaka has to battle against the more closed defences of the smaller Italian clubs, who try not to leave much space, while in Europe they tend to be more open."
