I belong to a gambling forum, 'RaceCaller', and by far the most successful guys on there are those who dabble in the 'anytime scorer' market. Regular scorers such as Aguero, Kane, Sanchez, etc, figure prominently and, obviously, the prices are not always tempting, but, unless you are completely inept, you are almost guaranteed to show a profit. If i select, say, Aguero and find he is an unattractive price, i add City to win for a score/win double, which is usually a decent price.
