2 match in a row save us time to not wait for a long time. i want my 2 match 15 minutes, it's good.

you can change EVRYTHING with 15 minutes ---> 7 minutes to next match start when the 1st end.----> 3-4 minutes to change formation, player, moral, condition.
you complain beacause you have only 11 player who can play.
