That's a fair observation, even though a lot of the teams he had a strong core but were just missing that last piece of the puzzle. But really, the exact same can be said about us in the past decade and we've had some of the best managers in the world. You need a lot of things to fall in place for you to dominate. On the other hand, Wenger has masterfully managed Arsenal finances and phenomenally oversaw their transition from Library to the Emirates while maintaining the a positive balance. That is an incredible feat. He's always been selfless and worked for the future of the club rather than his and his current team's immediate glory. For me, he's one of the most complete managers.
