One stands top of the table, the other seventh. They are surrounded by the striking greats of the Premier League era and, rather incongruously, Adam Le Fondre. They sandwich Sergio Aguero, Harry Kane, Thierry Henry and Ruud van Nistelrooy. They both lead Luis Suarez, Robin van Persie, Alan Shearer and Michael Owen.
They are Kelechi Iheanacho and Javier Hernandez. The Nigeria international has the best goal-per-minute ratio in the division's history, while the Mexico striker is not far behind. Iheanacho averages a top-flight goal every 106 minutes in England; Hernandez, one every 130. They are defined, distinguished, differentiated and (curiously) damned by the numbers.
