Should Olympic football be replaced with 6 a side or futsal as an alternative?

I would be totally against that. The Olympic Games have been an embarrassment for a while, the madness needs to stop.

3x3 basketball is an abomination and breakdance was the low point since 1896.

Football should remain untouched, except lifting any restriction on age and/or selection.
 
Futsal absolutely

And 7-a-side if they want football too imo
