You could never remove subjectivity as the most are not set in stone, it's the main reason why the whole idea is a load of shite (alongside how it removes some of the fun out of scoring goals due to the uncertainty as to whether or not it will stand)
The replay shows the ball deviates slightly which means he touched the ball. They fucked up.
Touching a ball slightly doesnt mean that it isnt a foul..
It means he won the ball so unless it was reckless (or he does something else like pull the player down with his arm) then aye it literally does.
Aye I want Kennedy too, I think Townsend would be competing with Ritchie and not him in anycase.
If it's a case of us getting only 1 winger in, or we want a more attacking winger alongside one of those, then I'd go with Kennedy.
