Jose Mourinho personally intervened to stop Roma fans aiming racist chants at AC Milan striker Zlatan Ibrahimovic on Thursday evening.
Milan ran out 3-1 winners at the San Siro to stay within one point of bitter rivals Inter at the top of Serie A.
It was a tasty encounter and Roma ended the game with nine men after Rick Karsdorp and Gianluca Mancini were both sent off.
Things turned ugly in the stands sadly, as DAZN report Roma fans aimed a 'racist song' at Ibrahimovic in the 77th minute.
Roma boss Mourinho, who has worked with Ibrahimovic at Inter Milan and Manchester United in the past, took matters into his own hands and pleaded with the away support to stop.
Reports have claimed the Sweden international may have been called a 'gypsy', the same insult used when the two sides met back in October.
A club statement at the time read: "We have zero tolerance for any form of racism. The club has been committed to combating racism and any form of discrimination for years. As an organization, we continue to do everything we can to change the behaviour of some fans in a positive way."
Milan took the lead inside eight minutes after Tammy Abraham handled a Theo Hernandez strike and gave away a penalty.
Olivier Giroud stepped up and converted for Stefano Pioli's men.
Junior Messias doubled Milan's lead less than 10 minutes later after turning home a Giroud shot which bounced back off the post.
Abraham did give Roma hope just before half-time after a clever finish, which caught out Mike Maignan.
The second half was a much closer affair until Karsdorp was given his marching orders for a second yellow.
Rafael Leao scored to seal victory for Milan who had the chance to get another in injury time.
Mancini hauled down Leao in the box and Ibrahimovic stepped up hoping to score his first of the year.
Rui Patrico matched the 40-year-old and produced a fine save to keep the scores at 3-1.
Roma are seventh in Serie A and six points behind Atalanta in fourth.
