Ancelotti unhappy as AC Milan continue home struggles
Clarence Seedorf had opened the scoring with a lucky ricochet just before the break, but Andrea Pisanu's volley earned the Gialloblu a point.
"We cannot always be sharp and at times you have to grit your teeth and bear it," added Ancelotti.
"I have to compliment my lads, but I also tell them to work hard. On Wednesday we have another important match."
