Having converted 29% of their shots on goal, West Ham are the league's most clinical finishers so far this season.
The Hammers got off to an outstanding start to the campaign, beating Man City, Arsenal and Liverpool away.
Claudio Ranieri's Leicester, who knocked West Ham out of the League Cup earlier this week, are the only other team to have converted over 20% of their shots.
West Ham take on Norwich at home this weekend, hoping they can extend their run of good form in front of goal to move above Man Utd in the league.
