I think the difference between Luiz and Koscielny represents one of the reasons why fans are beginning to lose patience with Arsene and his policy. We could have signed Luiz in July, no questions asked. Alright it would have cost us at least £20M, but we could have got him no problems. Instead we go and get a completely untried and untested unknown quantity from France, for less than half the price.
I like Koscielny and think he will turn into a great defender, but it will take time to knock the rough edges out of his game, and it was one hell of a gamble to throw him into the team as we did. We could have taken much of that gamble out of the equation, if we had paid more money. It's the sort of gamble Spurs would take, or Villarreal would take, because they just can't attract the top players and never win anything anyway, but never one of the big boys - simply because the pressure to win and succeed means there's too much to lose if it goes wrong.
Maybe we need to start thinking and acting like a big club, one who can't afford to take gambles because it might cost us a trophy - which should be considered the end of the world if it happens. We don't have the money of some other clubs, but there's definitely an element to Wenger where he wants to show people that there is another way to win - and that means he doesn't get everything he can out of the budget he has available to him.
I think that's where the extreme frustration with him comes from because he's just so damn stubborn, almost like he's trying to show everyone how clever he is. I think that's the next stage we've got to move onto; thinking and acting like the big club we now are - hopefully Wenger can adjust his thinking and change his approach, but I fear it might have gone too far for him to do so.
