Bring in a new coach, new ideas, not afraid to spend, someone tactical yet a passing purist.
If people sit back and genuinely reflect, they will see that Wenger is a coach who can do okay and thats down to his genius, however the modern game has moved on and now genius is not enough, you need to prepare to the last letter and set up your team in the right way each game.....all the best managers do it and its no coincidence that we lose so many big games now and have done for a while as Wenger just wont embrace this side of the game.
