hi trouper!! i think its easy to manage. i would give a massage to the players twice to 3 times a week, one after the match, tuesday and thursday. seems that the players have a though programm with only 2/7 rest days. wednesday is a good sauna day. make sure that athletes rehydrate properly, that the reason for no sauna 48 h prior to competition. injury risk might be increases, because body is in a kind of regeneration phase concerning to hydration but also immunsystem, cardio-vascular etc.
most important is to make sure that athletes cool down properly and have an adequat stretching programm. that plus massage would be great.
take care.
