I think it's a bad idea ... you are talking about playing in 4 competitions in one season? it's bad so and so mad.
the team which play 2 games a day always have problem of resting his players, so what if make it 4 games a day? I know it may be from time to time not every day but it's not logic specially if we are talking about the great managers who compete till the end in all competitions L CL CUP WC .
So for me it's not working![]()
