AC Milan were foiled by heroic goalkeeping from Empoli's Pietro Terracciano as they were held 1-1 by the promoted side on Thursday, their third successive Serie A draw.
Milan got off to the ideal start when Lucas Biglia's volley was deflected into the net off Empoli's Leonardo Capezzi in the 10th minute.
Terracciano denied them a second goal before half-time with a double save from Giacomo Bonaventura and he also blocked Franck Kessie's effort from the rebound.
Milan then gifted Empoli an equaliser in the 71st minute when Biglia gave away a penalty after Milan captain Alessio Romagnoli had sent an attempted clearance straight to an opponent. Francesco Caputo converted the spot kick.
Terracciano then capped his outstanding evening with a superb save to turn Suso's shot around the post, leaving Milan with six points from five games and a modest 13th in the table.
The game marked the fourth time so far this season that Milan have conceded an equaliser after taking an early lead, the most in Serie A.
