AC Milan midfielder Kaka accepts the club is under pressure to turn their season around.
The Rossoneri face Champions League opponents Celtic on the back of a run of games that have seen them go seven without a win.
"We are always under pressure in Milan," said Kaka. "Seven matches without a win, it means there is more and more pressure to win the next game.
"And it will be against a very difficult opponent.
"The atmosphere [at Celtic park] is amazing. A few of my teammates have played here before. It is never easy against such a great support. It will be the same tomorrow.
"For the moment, the big problem is that we cannot win. At the moment, we need to win. Tomorrow, we will try to win whether we have a good or bad game.
"It is very important for the group that Milan win three points. The atmosphere is a bit tense in the changing room but sometimes it is a motivation."
