Yeah, it was reckless and could have been given - but for me Gordon's was much more clear. Gravenberch's is a 50-50, some will give it and some won't. 90%+ will give a red for Gordon's tackle.
The only difference was Gordon's pace; it was a one-foot tackle, and if he hadn't taken so much speed, running from the far left to make a tackle in the middle, it could have been a yellow if it was a close-range tackle.
Please don't start with the conspiracies, Bournemouth's handball in Round 1 was a red card as well - and it was not given. You win some you lose some, same for all teams other than Fergie's United.
Not longer a conspiracy when every club fan base sees the same thing every season - this is the not the first place you're hearing this ?
After the Fergie era ended, the PGMOL needed a successor, and Liverpool was the obvious choice. There's a reason why the comments section is disabled on PGMOL Var social media pages.
