Another day, another Romelu Lukaku goal! Yet again, the Inter Milan forward found himself on the landmark sheet with his strike against Cagiliari in Tuesday's Coppa Italia clash.

Having entered the encounter with four goals from his last three appearances, Lukaku needed less than a minute to flaunt his efficiency in front of goal one more time. In barely 21 seconds, the former Manchester United striker latched onto an erroneous pass in the visitors half to slam in the fastest goal scored by any Serie A player across all competitions this season.

After his first-ever Coppa Italia goal for Inter, the Belgian attacker was called into action one more time to finish the proceeding with a brace. This time, the 25-year-old striker headed home a cross four minutes after the second half had resumed.

In essence, the attacker's brace in the 4-1 cup win made him one of five players to have scored two or more goals in at least five games across all competitions in the top-five European leagues this season. So far he has scored 20 goals and has registered four assists in all competitions this season.
