Recommendation for Arsenal

Its been just a couple of weeks pass after the EPL had started... I must admit as an Arsenal fan...I am worried... Not because that Henry left... but its the Keeper and centre back... As for Lehmann he is getting old and starting to show the signs which in the past David Seaman suffered before he retired. Maybe its time for a new young keeper to step up. As for centre back lets face it... arsenal don't really have enough cover.. the best cover they had already out on loan to Birmingham... they better find one soon... now is still early in the season most mistakes are able to get away easily but not when the season be in full swing... on the topic of beefing up they should consider an old fashion centre forwrd who will finish off all their hard earn chances... by the way thats what i felt .. any of you guys got any opinion?
