Kevin Prince Boateng says he still feels upset AC Milan drew against rivals Inter in the big derby last Sunday.
Stephan El Shaarawy opened the scoring for Milan after receiving Kevin-Prince Boateng's through ball and flicking it round Samir Handanovic with the outside of his right boot.
The goalkeeper could do nothing about the 21st minute strike - but spent the rest of the half denying Balotelli and his team-mates with a string of super saves.
Milan's dominance was largely down to the work of El Shaarawy and Mattia de Sciglio down the left flank.
This was stopped after the break as Zanetti moved across from left back to right back to deal with the danger.
Abbiati, who had a quiet first period, was called in to action as Inter woke up in the second half.
He saved superbly from Freddy Guarin, who could not believe his effort from 10 yards out following Rodrigo Palacio's cross did not result in the equaliser.
But that came soon after when Argentine midfielder Ezequiel Schelotto came on as a 69th minute substitute and two minutes later headed home Yuto Nagatomo's cross.
Inter continued to press after that but could not break through, as Milan fell away.
Boateng says he is upset his side failed to pick the maximum points.
“It was a tough match, but I’m a little upset because we had to win it in the first time.”
The draw left Milan third, six points behind second-placed Napoli and 13 points behind Serie A leaders Juventus.
Inter are one point behind Milan in fifth.
