5) Son Heung-min – Tottenham – £190K A Week
The South Korean international won the Golden Boot back in May but he has looked like a pale shadow of his former self so far this season.
Son has scored in just two games; a hat-trick against Leicester in September and a brace versus Eintracht Frankfurt last month. Much more is expected of the 30-year-old, who has (on the whole) been outstanding during his seven years in London.
