The Rossoneri coach says he did not see Matri's equalising strike but ponders how the complexion of the match could have been different had his side been given the second goal
The Rossoneri took the lead in the first half after Antonio Nocerino capitalised on a howler from centre-back Leonardo Bonucci, before Alessandro Matri's late strike ensured a share of the spoils.
Both sides had a goal controversially called off when Muntari's header was picked out of the net by Gianluigi Buffon after it had crossed the line, and another of Matri's shots was incorrectly adjudged to be offside.
Speaking to Sky Sport immediately following the match, Allegri said it did not feel like two points lost.
"I wasn't upset at the end of the game. It was a beautiful game played very well by Milan; regrettably there was that episode that affected the game.
"The [cancellation of Muntari's strike] harmed us because we would have been up 2-0. Maybe we would have drawn all the same but the game would have been different," he noted.
"Matri's goal? I didn't see it to be honest. It would have been the tying goal or just 2-1 if they had given us Muntari's goal."
The draw keeps Milan just one point ahead of Juventus in the standings, although the Old Lady have a game in hand.
