Have seen/heard a fair bit about Kozak's goal scoring record, most notably the fact that while he scored 10 in 11 in Europa League last season, he also managed none in 19 apps in Serie A last season!
Thought I'd look a bit more at this, and found the following quite interesting (dunno if anyone has mentioned this before here...)
Career minutes per goal (from transfermarkt, includes International and youth internationl games in some cases):
Benteke - 171
Weimann - 173 (including Reserves/U19 league games! 216 not including these)
Kozak - 177
Helenius - 181
Bent - 182
Agbonlahor - 335
If this is anything to go by, with Kozak (and Helenius) we may well have got ourselves a couple of Benteke-esque bargains this transfer window.
