Redknapp's a good manager and he did very well for us, but he's hardly in a position to criticise the Director of Football role. He certainly didn't seem opposed to them when he became one at Portsmouth, something which he later claimed was never intended to become a managers job. I'm not convinced that he's capable of maintaining a successful run at the top in the Premier League without vast spending or the influence of a DoF. His transfer tactics make perfect sense in the short run, as he buys experienced PL players who are around the top of their game, which undoubtedly works. I don't think that most clubs can sustain that sort of spending, though. I can't help but believe that the timing of this statement is quite self interested, as it wouldn't be that surprising to see QPR considering bringing one in. He doesn't like working under one anyway and I can understand that, but I think that any club should that employs him should have someone in a similar role, if not identical. The youth system, squad size and turnover of players would be a concern for me, if I were a QPR fan.
Actually if you look at the players Redknapp had, the best ones were signed by Comolli not him. Its quite ridiculous to suggest that he was single-handedly responsible for our fourth placed finishes. As for Levy's success in hiring - we added £Ms of value from the signings made while Comolli was in charge and almost none from those signed while Redknapp was in charge (when we also sold two or three of Comollis signings for below their current value). All the 'facts' suggest that Harry is completely wrong about this. Its a real pity because he is a good coach but hopeless at identifying talent. He and DoF should be a perfect arrangement if only he could get his ego and fear of failure out of the way.
Levy is a very good chairman if you want your club to make money. In footballing terms he is god awful at best. Always shifts blame but ultimately he has Spurs best interests at heart.
