I'm still not entirely sure what the official PL stance is regarding when linesmen are meant to flag for offside and when refs are supposed to whistle for it? Seems different every time.
It’s the main thing that needs addressing.
It should never be wrong again
Firmino goal v Villa is a perfect example. Put his flag up like ‘fuck VAR I’m still important’
Linesmen could effectively be completely replaced now and they know it
