Inter Milan dropped their first two points of the season when they were held to a 1-1 draw by Lazio in a bad-tempered Serie A match which saw one player from each side sent off on Sunday.
Lautaro Martinez gave Inter the lead on the half hour after the ball ran loose in the penalty area and Sergej Milinkovic-Savic equalised for the hosts 10 minutes after the break before tempers flared.
Lazio had forward Ciro Immobile, topscorer in Serie A last season, sent off after 70 minutes following a clash with Inter midfielder Arturo Vidal although the Chilean reacted theatrically to what seemed like little more than a prod.
Inter, who have seven points from three games, also finished with 10 men after Stefano Sensi was dismissed following a clash with Gil Patric. Lazio, fourth last season, have four points from three games.
