There is a big difference in buying players who fit the system and seeing them fail compared to buying players apparently completely alien to how the team plays and then failing as a result.
So why is Wenger buying Vardy?
You don't think Wenger has signed players that have been poor fits for his system in the past?
Managers are not perfect at figuring out which players fit their system or not. It's part of why transfers sometimes (or often) fail. Wenger is no exception to this. Going by your logic every signing Wenger ever makes fits the system and criticizing them makes no sense.
