Football is a game of opinions.
It's a game where everyone is an expert and where everyone thinks they know best.
When we're watching the games, we all know where the ball should go but executing it is the more difficult thing.
If it were easy, we'd all be earning millions in the top flight.
The same goes for any job.
If you know what you're doing, it's simple, but in virtually every walk of life, the changing economy, the advent of new technology and the movement of communities means that new challenges face us every day and every week.
Take Arsene Wenger. He was a pioneer of training, diet, scouting for talent no one had heard of and of making a team competitive without spending big.
He remained calm when others around him lost their heads and he took the brunt of criticism and abuse when things went wrong regardless of whether he was doing so out of loyalty to those above him.
Of course, he has got many things wrong and you could argue that the game has moved on while he has in some respects stood still.
After Villa, I defy anyone to have found positives in the manner of our defeat or the situation it landed us in. Doubt spreads easily.
After naively suggesting that we could compete with the big boys now, the club needed a statement signing. In Mesut Ozil, we have one.
Of course we could have done with a striker, with a defensive midfielder or a winger and certainly a defender but the late nature of so many big deals underlines how difficult it is to buy and sell between the top teams.
As others have said, the signing of Ozil is up there with the signings of Alex James or Dennis Bergkamp.
It is a statement of intent, of the ambition that the German himself spoke about., of finally starting to fulfill the competitiveness that was promised when we moved to Emirates.
I have no doubt that new arrivals will come in January as well, those pushing for a World Cup place and not getting the exposure or the opportunity to force their way into national plans, perhaps.
I'll admit it. For the first time I really started to wonder whether Wenger had reached the end of his time at Arsenal.
Without robust advisers or fresh thinking, people become stale and that can be catastrophic for a club.
But let's not forget - we have been in the top four for 16 straight years, something never before achieved in our club's history.
If the financial shackles are not coming off, maybe Wenger can start to erase the pain of the stadium move and help us win the trophies we yearn for.
