I've actually played the game at high enough levels thanks.
You know what my proof is on it being the right decision, garnacho scored easily.
All he had to do was stay onside because Rashford gave him a perfect one on one which he EASILY finished.
You're joking right?
Rashford played the right ball, all Garnacho had to do was keep onside, all their defenders were behind both Rashford and Garnacho.
That's completely on Garnacho
That offside and the shot at the far post instead of laying it off to Hojlund for an easy tap in, he has to get these right. They're simple, simple decisions and if they go in, it makes the game so much easier for us
That's the bit there, which makes it case closed and 100% penalty.
He gained an illegal advantage through his own actions. Lunging at the ball and making your body bigger, covers where the ball can go.
