The foam is there for a reason.
Is it ok to move the ball a yard down the touchline for a corner ( it’s not closer ) but the quadrant is there for a reason.
The keeper didn’t reset the wall that I remember.
Is it clever yes.
Cheating yes!
The foam is really there to keep ball and wall ten yards apart. Toney hasn’t breached that ten yards - he’s changed the angle by a few inches. I’m not even convinced the referee would have asked him to replace the ball had he seen what was going on!
Funny and clever in equal measure, but the main issue here is that no player in that Forest wall was switched on to what was happening. No real sympathy with them, and I’d really class it as gamesmanship rather than cheating.
