Sandro Tonali has scored a late winner as AC Milan earned a crucial 2-1 comeback victory at Lazio to return to the Serie A summit.
Milan found themselves on the back-foot as early as the 4th minute when Ciro Immobile poked home a cross from the right flank.
However, the Rossoneri restored parity early after restart thanks to a brilliant effort by French striker Olivier Giroud.
Milan completed the turn-around at the death as Zlatan Ibrahimovic nodded across for Tonali to force home and spark wild scenes of celebration. The win puts AC Milan 2 points clear of Inter who have a game in hand. Lazio stay seventh on 56 points.
