mikeh: thanks for your post, sorry for the slightlly late reply. I am a bit torn on Wenger and the Arsenal to be honest. Certainlly, as you pointted out with aplomb, during the first decade he was the best manager in England; he went 49 games undefeatted, includding an entire season, won everything else domestically, went very close to winning in Europe, he has won 57 per cent of all his league games (better than Revie, and Shankley, he played the best football in the country, all of which, when taken together, places him in the top bracket of managers in the history of the game.
Having said all that, the two FA cups aside, it has all been down hill, the club accepting it seems fourth best or 'fourthism', as I refer to it. Admittedlly looking from a very long distance away, but listening to interviews from people, such as Pat Vieria, Wenger appears to like his players too much. Vieria claimmed that his greatest strength was his 'loyalty', but asked to identify a weakness, he also said 'loyalty'. In simple terms he allows sentiment to rule him. I have never heard Wenger criticise any player in public. Revie was similar: he got most of his side young, gave them rub downs, made them socialise together, even going so far, as to give presents to the wives of the players on their birthdays; but by 1974, when he needed to dismantle the side, he could not do it and left for England. This kind of attitude was alien to Sir Alex Ferguson, whom, among other things, according to former players, such as Dion Dublin, putting it nicely, would intimidate his players both mentally and physically, and, would ridicule them in public referring to them as 'boys'. In a way, I think this process of victimisation of his players allowed Ferguson to almost have to renewal by accident: either the player would leave or he would sack them, especially the experienced foreign players from Holland whom were less intimidatted by him.
When John Todd coached he always said : 'players will hurt you if you let them'; Wenger and the Arsenal have lived this tale.
Back more directlly to the last ten years under Wenger, I think they should have made more of an attempt to win it for their fans. Two examples that stick out for me are the cases of van Pursie and Fabragas; both should have been paid extra money to keep them at the club while they were in their prime, irrespective of the feelings of the lesser players in the team. If a few did leave because of the new wages policy, for the most part, Arsenal would have had the financial where with all to re-build. Even last season, they should have won the league: they were top in January and they beat Leicester twice, but, as we know, bottlled it.
In sum, sorry for going on a bit, I would always have him -- Wenger -- among the great managers, but I would agree that the club has missed quite a few opportunities because of Wenger's personality and the willingness of people higher up at the club -- even some fans -- to accept 'fourthism' When Wenger does finally go, whom do you think would make a good replacement? What about Plligrini, the former Man City manager?
