AC Milan continued their perfect start to the new Serie A season with Friday’s straightforward 2-1 win at Roma who struggled even after Romelu Lukaku made his debut from the bench.

Milan were the better team throughout a niggly contest and had the lead in the ninth minute when Rui Patricio was judged to have kicked Ruben Loftus-Cheek after the England international miscontrolled the ball while charging through on goal.

An outraged Mourinho sarcastically applauded the decision on the sidelines before veteran France striker Giroud stroked in his fourth goal of the season.

The away side would have been two ahead in the 22nd minute had Patricio not made up for his previous clumsiness by brilliantly keeping out Christian Pulisic’s close-range volley.

But there was nothing Patricio could do about the goal which doubled Milan’s lead, Leao getting goal side of Zeki Celik and brilliantly placing Davide Calabria’s cross in off the post while falling to the turf. “I’ve been trying to score that goal for three years!” a delighted Leao later told ‘Sky Sport’.

Milan were firmly in control until Tomori was sent off in the 61st minute for a pointless foul on Andrea Belotti, and with 20 minutes remaining Mourinho rolled the dice and brought on Lukaku.

However, a snapshot not long after being brought was all the Belgium striker managed to drum up in a finale which was made frantic after Spinazzola’s effort was deflected past Mike Maignan but didn’t change the final result.
