The first thing for a pen is for a forward to 'go down'. If yer don't hit the deck yer getting nowt. Doesn't matter if you've been held or pushed. If yer don't go down there'll be no pen and for a good number of seasons players like Ash the Crash and others, Salah lately, have perfected a tumble to look as though there has been a push or a trip when they have allowed gravity to drag them to the grass. And if there is sufficient touch similar to the ball hitting Laporte's arm on Saturday that will do for Dipper and Rag ex-pundits to scream penalty. But after hitting the deck there is a quick check on the shirt colour. Pastel colours don't even get a referral to VAR. I suppose that Oliver thought the sky had fallen in for a second or two when Lamela tried his wrestling move on Rodri, and succeeded in dragging him groundwards.
There are many on this forum, myself included, who welcomed the arrival of VAR, whilst others suggested that it wouldn't make the slightest difference to match outcomes. The way it is being applied and misapplied I fear the latter group were right.
