We're missing an integral part to success and to me its David Dein.
In addition to Eden Hazard and 4-4-2, I assume?
Seriously, in my humble opinion it's naive to think of Dein as the Messiah. He left Arsenal five years ago, and football and Arsenal have moved on big time since then. I am not saying that he is completely out of touch with football, but you cannot assume that he would come in and do a good job under completely different circumstances and in completely different structures at the club. In addition to that, let's not forget that the contractual situation at the club was far from perfect under Dean. Wiltord, Kanu, Flamini and Edu left for free, Hleb invoked the Webster clause, Henry was on huge wages so we had to sell him under his market value, just to mention a few. Let's not forget that Dein wasn't some kind of miracle worker. I don't want to downplay his successes, but there's no reason to glorify his influence and his skills either (basically, this is the Wilshere effect).
Secondly, it's not only naive but also desperate to wish for Dein to come back. He left the club, with £75m in his pocket, he sold his shares to Usmanov. Two fingers up for the plurality of ownership of the club, and a massive profit for him. If "his love for the club is next to none
", as you say in the opening post, I would like to ask why he decided to sell his shares in the first place, and to Usmanov of all people. If you love the club that much, you don't sell out to Usmanov, and not in the circumstances in which it happened.
What kind of forward thinking is this anyway? Things aren't working out, and on top of bringing back Henry (not to mention Campbell and Lehmann) we bring back Dein? Those figures were important in the past, but we should move on and try to implement new characters that have their own influence on the club.
