Yep it has to be a priority. It's odd. Wenger usually feels more inclined to add attacking players when dipping into the market, yet it's not the first time we've lacked depth in the striker department. Remember that time a few years back where we had to play Arshavin as a lone striker (albeit he did really well all things considered)
I yearn for the day when we had options like we did when we had Bergkamp, Henry, Suker and Kanu and flung them all on the pitch when chasing games
