Dont think you can, A quick google search suggest you bought a copy from the Europe region.
PS3 games have a code on the bottom side of the case.
BLES (Europe and Australia / New Zealand)
BLUS (North America, including Canada)
BLAS (Asia)
I would suggest returning the game, If that isnt an option try selling it on ebay and buy a copy with the BLUS region code.

Some games have no option to change the language. This may be one of those cases. If it is possible to trade it for an English version then do that. Your PS3's language settings has no effect on that.
