Its not. Its not a push like the Fernandes did with the linesman. There is aggression in Weghorst, and he uses his fist and punch him in the shoulder. Does it change the result? No. Does he the Forest player take any harm? No. Its a clear red.
And if the VAR is correct then? That stat doesnt show anything if its wrong or right. Burn handball got vared, same Isak against Brentford. Maguire got away with it. Fernandes got away with a kick in the head with Schar. Its bullshit
