Speed is almost essential for any player wanting to play on the wing. Strength and agility are also useful attributes, to run through and dodge tackles. It is important that wingers attack the space, but also look out for other options, like supporting players.
Wingers should always make themselves an option to the ball carrier, and attempt to catch any kicks sent in their direction and obviously one of their main jobs in open play is to try and score for the team.
Wingers should be prepared to beat more than one player each time they receive the ball so quick footwork and fakes will come in handy in these situations.
