Inter Milan bounced back from a controversial Francesco Totti penalty to snatch a point in their 1-1 draw with Roma on Sunday.
In a match that was characterised by Roma’s wasteful finishing, the capital side went ahead after 20 minutes when Michael Bradley was adjudged to have been brought down in the box by Andrea Rannocchia despite replays showing minimal contact between the pair.
Totti stepped up and struck home the resulting spot-kick to give his side the lead, sending the partisan crowd at the Stadio Olimpico into raptures.
Roma then began to control proceedings but could not convert their dominance into goals and were made to pay when Rodrigo Palacio tapped in a Fredy Guarin cross to level the scores on the stroke of half-time.
The second half saw Roma once again fail to convert the plethora of chances that fell their way with Inter goalkeeper Samir Handanovic pulling off a number of brilliant saves as the visitors held on for a share of the spoils.
The draw leaves the Nerazzurri nine points behind Serie A leaders Juventus in fourth while Roma sit a further six points behind in seventh.
Meanwhile, Facundo Roncaglia scored an unlikely goal from his own half as Fiorentina held Napoli to a 1-1 draw.
Roncaglia gave the home side the lead in the 33rd minute when his wishful ball was misjudged by goalkeeper Morgan De Sanctis and bounced into the net.
But the advantage lasted just nine minutes before Edinson Cavani levelled proceedings with a powerful header.
