Depends on the individual.
Problem is, any proven striker will
a. Have to want to play for us, and
b. would have to be fairly cheap, unless JH has a nice surprise for BR.
Price aside? I'd rather have a proven striker. (Proven in a premier league somewhere, not the nPower)
Both Suarez and Torres have proved to be great pieces of business in recent years. Both fees were relatively high but the wages of each were modest at their existing clubs. There is no value in the premiership as the taylor fletcher to Sundreland for 11.5mil transfer proved. Spain is a good place to shop right now as clubs are struggling due to recession, Germany is the up and coming league with many a good young player available. Dutch league offers skill and technique at good value but not every player settles from there.
I feel a south american punt would be our best bet, hunger , tenacity and skill in abundance.
