A talented winger will receive a pass, survey the options in the box and pick out a team-mate with a pinpoint delivery.

But, making the most of balls into the box is not just about the quality of the cross, there are a number of elements that have to come together.
"There are two elements - obviously the delivery is the most important thing and the timing of the run is the next important thing. One without the other is no good,” Carr explained.
"We're looking for quick, early finishes and good early, quality crosses. Whichever technique you're going to use, you've got to keep your head down and look at the ball.
“Too many players get their head up too early, looking where the cross has gone before they've delivered it. It's crucial to watch the ball and not take your eye off it, until you've made contact."
Motivate your players to get the ball into wide areas and punish the opposition with this drill from the Hammer's youth team boss.
