Don't worry.... Super Stevie Bruce is a mastermind when plan A fails to work.
Bruce chose to go with 1 upfront, a player who isn't even a recognised striker and cannot shoot for buttons, even though he has two strikers on the bench who he paid 10 million for during the summer, a time when Arsenal are conceding goals left right and centre.
Now Bruces plan A hasn't worked, let us take note how long that it takes him to change the formation. Let us use this game to thoroughly examine what Bruce does to prove that he is a managerial tactition with enough footballing knowledge to change the game, or even attemmpt to change the game.
If plan A doesn't work, then a competent manager must adapt and put into practice plan B. Let us see what Bruce does to implement plan B.
