Wenger going to Real Madrid. They have money to spend unlike Arsenal. The sad truth is- Silverware is the yardstick for success just as Island Scholarship is the yard stick for a good school in Trinidad. A side is as good as its bench. That is Wenger's problem when injuries step in plus he needs some experience with this side.
But Arsenal always said they had money if he needed, he just didn't believe in spending exorbitant amounts on players when he saw his kids as being enough. I think that year when he spend big money on Reyes (who end up abandoning him) and then he saw Fabregas become a star almost immediately (that same year I think), it kinda burn him. He start to believe that what is the point of spending when my youths making the step up instantaneously?
But maybe Arshavin will give him faith in spending a little money again.
If he goes, it have plenty coaches out there available...even Tony Adams might do well as it have an Arsenal structure in place already that he just have to fall into. O'Leary is a big Arsenal product too...he was a decent coach at one point. And that is not talking about all the Rijkaards, Mancinis, Ranieris, Klinnsmans, Van Bastens, Scolaris, Erikssons and all the national team coaches who will be unemployed by November when their team look to be out of the race for the World Cup.
Arsenal is an excitiing proposition for anybody. All they need is to buy a big player a year ($15m to $20m) for the next 2/3 seasons and they will be a big side again.
That's what ManU basically did. They had their homegrown talent then they spend on Rooney, Ferdinand, Berbatov, Tevez...basically one big buy a year, while they had Vidic and Ronaldo and young talent on the (relative) cheap. Arsenal have that part already..is just the one big buy a year.
This year it should be a central defender who is a leader. The midfield could hold on for one more year with Nasri, Arshavin, Fabregas and the youths. And they should lose faith in Bendtner and unleash Vela, Walcott and Eduardo alongside Van Persie (this is assuming that Adebayor leaves).
