The team that talks and communicates well with each other stands a better chance than one who is silent.
You waste energy and time by going sideways. A good team have no trouble defending this.
Play the Whistle
The ref has control of the game, don’t stop because you think he got it wrong. And whatever you do don’t argue.
Be it the defender claiming a touch, or a ref deciding it was a forward pass, respect the decisions made and play the game fairly.
Aim to be on the pitch for only two to three sets of six. This keeps the game fast and gives everybody a good amount of playing time.
Touch is fun; even at an international game the atmosphere is friendly and good-natured. Play the game in that spirit.
