The referee and their officials and the VAR team know there is no Var definite camera angle at that end.
I don't know if same at other end or not.
As they are aware of this they know if they raise their flag, the VAR team will not overule that raised flag.
That brings open to abuse and corruption into play.
To prevent that opportunity, VAR should use whatever imagery they do have to see if it verifies an offside
Or not. If they cannot verify an infringement, in this case offside, then the goal should stand. Even moreso
this year, where if Lino is correct but they apply thicker lines, then the Lino red flag is overuled by VAR.
