How long a contract did we give Silvestre? still by far the most bizarre thing Wenger's done frankly, he must be on fairly hefty wages, old player, utterly useless and past it and we bought him at that stage.
WE really don't need a replacement for Ade though, waste of wages. Frankly starting this season all looking to be completely fit are RVP, Eduardo, both truly and utterly world class, Vela, Bendtner, Theo, and lets be honest, Arshavin, Nasri both are "withdrawn/support" strikers who do much better through the middle, Rosicky is really a central attacking mid, Denilson is really only useful inside the penalty box(all his assists and shots (on target) come deep inside the box. We're a club completely overflowing with central heavily attacking biased players.
With two strikers in Eddie/RVP that really any club in the world would start, Bendtner whose very powerful in the air and got 9 goals in the league in 17 starts, which is pretty damn impressive, with almost none of those appearances in his prefered role(he's a withdrawn striker and when played there set up a bunch of goals for vela, and 9 at international level), Vela whose looking like a younger Eddie, Theo, whose a bit crap but meh.
When you look at Utd, they won the title with Arguably Rooney, Tevez and Berbatov as their only real strikers, with Wellbeck/Macheda not even close to as good as our "backup" strikers.
We simply don't need strikers and should ditch Ade without a second thought, we just need to actually play Eddie/Vela who were both vastly underused this year, and play bendtner consistantly in a single position.
