The Bianconeri and Milan battled it out in the second leg of the Champions League quarter-final last night.
The Giallorossi got the better of the Milan defenders early in the first half, but the Nerazzurri’s attacking options were not able to break through the midfield wall of Marcelo Brozovic.
At 1-1, the two sides had the match decided.
The Nerazzurs had a first-half chance to put themselves ahead when Gianluca Vialli’s shot was deflected wide by Gianluigi Buffon.
But it was not enough, and it was Milan who finally got on the scoreboard, when Gianluigio Buffon’s corner was headed by Stefano Pinturro.
Milan took the lead through Stefano Barzagli, who made a brilliant save to deny Andrea Pirlo from close range.
Then, after Barzagali’s penalty had been converted by Alessandro Florenzi, the Nerazio’s Diego Milito saw his effort saved by Gianlucio Carbone.
However, the Giallormen’s defensive frailties continued, as the second half went on.
After a great pass from the Milan goalkeeper, Alessandro Del Piero was denied by a diving Brozovski, and the Giallsioni’s captain Giuseppe Mancini was sent off for a second booking.
The result puts Milan one point ahead of Roma, and makes the tie the first in the group after six matches.
The next leg will take place on Friday evening (16:00 GMT), when Milan host Genoa.
