The reason Ch£l$ki need a Sporting Director is because they can't do what Madrid have been doing for years - buying the best every year - and with an eye on future UEFA rules on limiting the number of foreigners in teams, Chelsea need to sort out their youth academy and nurture some home grown talent as well as tapping up every years Ballon D'Or winner.
In Arnesen, they have bought a man with a key eye on talent as seen in PSV - though these players didn't come to their peak some years after they were first bought, which is again, why Chelsea have approached Arnesen. Chelsea are at the moment spending a "loan" from Abramovich which he accepts back in kind - hence Kenyon saying "we need to become self efficient"... i.e., not having to fall back on sugar daddy's money. We'll probably see less of that Russian clapping seal in the future, but he'll still be around to see his investment return him his roubles. Ultimately, Chelsea want to garner the best youth of Europe as well as grass roots and then try to get the both worlds in future.
However, the apparent email to Tottenham's hierarchy in trying to ask about Arnesen's availability, while copying him into the original email is not a mistake, but a sly attempt to unsettle someone who they know will bring profit to their "business". Money talks i'm afraid - as you can see from "Glass Ankles" Cole. There is little loyalty nowadays due to the inflated wages paid to players. You only have to see the inept captain of our national football team and his wages to realise the world they live in is just so far detatched from reality it is comical.
If they are found guilty of approaching Tottenham, I hope the FA throw the book at them. But as all you UK resident forum members know - the FA stands for the notion of what they tend to do in these high profile situations - F*CK ALL.
