Wenger On When To Change Formation

Transcribed:

To change tactics in the middle of that game makes sense, if it's efficient. And that's what you're judged on, and that's why you employ it as well. It is to identify where the problem is, when it doesn't go well and change tactics or players to influence the result of the game. I would say that maybe the difference between very good coaches and the average coaches is there - it's to make the right decision at the right moment in the game.

What we do not speak about as well is the timing of your decision is vital in the game, because you feel some times 'now has come the moment that I have to make a decision...if I delay now my decision, I put my team at risk'. And that's where you need many times courage to make sometimes audacious decisions. But, success, never forget that - success demands risk and courage. And that's why in this job it's very interesting as well.

It doesn't seem like he follows his own advice.
