So many things have now been introduced to soccer, maybe temporarily. They include :
1. 5 man changes for each team against initial 3. This might be to help the players who have not been training enough and not playing active football, not to be stressed out.
2. Introduction of rest time in between the game for each half. Again, either to help players : just as mentioned above.
3. Moment of silence before the start of match. Maybe in honour of covid-19 victims.
4. Introduction of short music, played maybe with just one music instrument.
5.Games are played without fans.
6.Games are played everyday especially La liga.
7.Water break for each half at 30 minutes of play
Most of those changes will fade as time goes on unless covid gets that new "return" in autumn.
I think that one change introduced here will stay and prevail and that would be :
1. 5 man changes for each team against initial 3. This might be to help the players who have not been training enough and not playing active football, not to be stressed out.
Reason why I don't like this change is because it will benefit big teams and hurt small less wealthy teams. Bigger teams will now be able to rotate even better and use wider bench.
