It's suggested that looking at the 'Minutes per Goal' ratio is perhaps the best way to measure how prolific a striker actually is. I posted some stats from last season on the "Kuyt scores more than Crouch" thread and this got me thinking. Below are the ratios for everyone who has scored 5 or more goals this season. Unfortunately it's league only as I got the stats from http://fantasy.premierleague.com. Glad to see Torres in the top 4, I'm sure he will finish the season top 
Player -- Minutes|Goals|Ratio
Adebayor---- 852 | 7 | 107mins
Benjani------ 884 | 8 | 111mins
Van Persie--- 590 | 5 | 118mins
Torres------- 652 | 5 | 130mins
Ronaldo----- 818 | 6 | 136mins
Anelka------ 888 | 6 | 148mins
McCarthy---- 772 | 5 | 154mins
Drogba------ 787 | 5 | 157mins
Keane------ 1035 | 6 | 173mins
Fabregas--- 1060 | 6 | 177mins
Agbonlahor- 1080 | 5 | 216mins
Kapo------- 1170 | 5 | 234mins
