I don’t think having the set no. of reviews would be a good way to go. I think it works better now where it’s used only when required.

Those penalty decisions would have been made without VAR, so the only way VAR would create problems is if a correct decision is made and then overturned in error due to VAR.
It seems people want it both ways, the ref could have spent five or ten minutes reviewing the William pen earlier and not knowing which way to call it but because VAR couldn’t prove it was a definite pen pretty much instantly, the game carried on.

There’s already enough breaks in the game as it is so we won’t end up spending hours on the pitch cos of VAR, especially after a big decision with players protesting etc., and waiting around for decisions to be made certainly hasn’t happened in the Leagues they use it abroad.
