Don't see the point of assistant refs when there's VAR operating, they have been hamstrung and rendered redundant.As technology improves surely it can be done in real time and eliminate linesmen? Some weird buzzer goes off when it's an offside
If you have to have someone on the field of play, think it might be better to have a ref in each half of the pitch, so they have less ground to cover and they can keep up with play more efficiently.
