Team-mates shouting 'leave it' to one another during attacking moves was once a big part of football at any level - but it is now banned professionally.

A famous example - and perhaps why the shout was outlawed - was in 2017, when Bournemouth's Harry Arter appeared to shout 'Jack's' to Nathaniel Chalobah when the England international was on the ball during a Premier League match.
The main issue was that Chalobah was playing for Watford at the time, and he thought the shout came from one of his own team-mates.
As a result, he left the ball, allowing Bournemouth to regain possession and push upfield.
Former referee Dermot Gallagher told Sky Sports of his belief that the Republic of Ireland midfielder should have been booked for the shout - but Arter escaped punishment.
