Everton midfielder Tim Cahill has revealed the secret to his aerial ability.
The Australian has told how a combination of good service and good early practice has helped maintain his undoubted aerial prowess.
"Ever since a young age, I've done a lot of plyometrics, jumping and working on things that actually work for me," said the 30-year-old.
"To make sure I can direct the ball to go in the goal when I'm up in the air is something that I make sure I train a lot for to make it work.
"You do so much sports science in football that you can always try to be better at different things in training.
"I suppose I'm lucky enough that I've got that spring but, once you're up there, you have to make sure that the execution is right and that you're strong enough to hold people off.
"These days in football, someone's constantly holding you, nudging you or pushing you, so you have to be a bit cute because it gets harder every year."
