I'd love to see Isco playing for Arsenal, massive fan of his, brilliant skills, low centre of gravity and can thread a pass.

Cazorla, Isco, Wilshere & Walcott would be fantasy football, especially if the Jovetic rumours have something to them in front of them. Realistically though, you'd need a midfield enforcer with those guys in the side to shut down counter attacks, and spending that sort of money (Isco, Jovetic & a quality DM) isn't something I can see us doing, new sponsorship or not.
I'd be glad to see the back of Podolski though, don't think he adds much to the side and is on high wages. Perhaps give him a second season, but even then it's hard to see him being worth the £18m plus around 100k/wk wages he's on.
The bigger problem is offloading all the **** players, in total we've spent around £100m over four years on their contracts plus the £20-30m it took the buy them. No chance of being a truly top side if your backup strikers are Bendtner, Park & Chamakh who are all out on loan anyway.
