Milan edge derby to trim Inter's Serie A lead

Pervis Estupinan's first-half goal proved enough for AC Milan to claim a 1-0 derby triumph at the San Siro on Sunday and cut Inter Milan's lead at the top of Serie A to seven points.Inter are still on track to regain the title they lost last term to Napoli, who are 11 points off the pace in third after suffering a series of injuries, but this result leaves them with more work to do.
