I'm surpised they don't have a direcor of football mode. I've always expected that to add it in but it never has been.
I think it would be very interesting and as far as I can tell it wouldn't be anymore difficult to implement than what they have.
I know you can do it by making your assitant manager I manage games whilst you holiday - but it's not the same as the utility to hire people like Mourihnho, Klopp, Simeone etc... would be.
For people who like singing regens espeically I think it would be enjoyalble as you'd blitz through seasons in no time as well.
