When the game restarted, Liverpool were given the ball, even though Forest had possession when referee Paul Tierney had stopped play.
Gallagher later told PLP: Kelleher hits Konate and then if you run it on, watch the referee.
"If you stop the pictures now, this is when the referee is whistling. He whistled when Hudson-Odoi had the ball.
"Now, the law states, if he (Tierney) had stopped it when Konate got hit by Kelleher, the ball would have to be dropped in the penalty area and it would be dropped to Kelleher. Not a problem.
"But the ball has been cleared from the box, Paul Tierney hadn't whistled and he should give the ball back to Hudson-Odoi, who would then have the ball uncontested. He didn't do it, for whatever reason, Paul Tierney didn't do that.
All it is is an incorrect restart in law. The fact that Liverpool scored is a bit of a red herring myself because it was 1 minute 50 seconds (later), which is an entirety on the pitch.
"The ball comes forward, it goes back, goes forward and even goes out for a throw-in. It's just an incorrect restart in law, for me, it doesn't directly attribute to a goal."
