Wenger is BY FAR the best purchaser of players...end of argument! But not all players are suited to the way ARSENAL play.
Secondly...only 4 world class players eh? That's 4 more than most other teams! But let's look closer shall we? Lehmann, Wiltord, Silva, Freddy & Cole are all world class players too. Also, we have 4 great young players who are on the verge of first team this year that may well go onto being world class, and a few to follow through after that...there is a flow coming through - but the team itself is quite young still, the oldest regular (other than the keeper & Bergy) is 28!
As for Pennant, he will get his chance - I am sure of that, but Upson wanted out - he could have been playing with Campbell by now if he stayed & be a perm England first choice, Wright has gone on to be above average & Jeffers has been almost permanently injured.
We don't NEED another centre half - tho one would be nice, we have Campbell, Keown, Cygan, Toure, Senderos all to contest 2 places! Then there is no number 6...YET!
