Is kick boxing classes good preseason training?

Lot of players do it like pogba and zlatan

Any sport other then the sport you play is great for preseason training. I read somewhere that some OS football teams get their squads to play basketball, boxing etc as it help develop different mussel groups and also changes the players thought process.  

That's interesting thanks 

Judo is best for strength and balance , but could never find anyone in queensland who did it.

It is useful, but not better than football specific training.

I've done martial arts  training for 15 years.

The roundhouse kick is identical to volleying crosses when shooting for goal.
