I see all them things as being out of the hands of the board at the time of the divide. However one thing that the board have got massively wrong and one of the very main reasons they have this toxic divide is a lack of planning. How so many players have been able to run contracts down to the final year is unbelievably shocking. I don't think they will make this mistake again, if they do they are idiots.
None of those things were out of the boards hands, you might see it that way, but you'd be wrong. They decide when Wenger signs his deal by offering a deadline. Sign by X/X/2016 or we will find a replacement. Same for the players. Sign or we'll sell you, you can't just run down your value as an asset. Or just give them the money and promises they need to sign.
It's what every other club in the world does.
