David James is one of England's most experienced goalkeeper and a veteran of numerous League, Cup and international campaigns.
David shares his tips for keeping yourself in shape - and keeping those strikers at bay.
WORK ON THE SIMPLE THINGS
I have a structure to my training which I stick to very strictly.
The simple things can make all the difference
When you've caught 20 crosses in a row it can start to get pretty dull, but it has to be done at least three or four times a week.
You have to do it to keep your body focused, and make sure the 'easy' things don't become a problem during the game.
That applies to all aspects of a goalkeeper's work - kicking, punching, diving...you name it, it has to be addressed.
I'd like to say it's really fantastic, but it can get pretty boring at times.
It's well worth it though, especially when it puts you in a position to play football for your country.
SCREAM AND SHOUT
Another really important part of being a goalkeeper is communication.
David says communication is key
I spend a lot of time shouting at my team-mates, so it helps if they know what I'm telling them.
And it's not just me shouting at them - they have to communicate with me as well.
It's vital to practise this on the training ground, without the noise of the crowd. That way, everyone will know what they're doing when the pressure's really on.
STAY WELL TUNED
A top-line athlete is like a Rolls Royce, and needs to be well looked after.
If the Rolls Royce is run on diesel it may not give the performance that people expect.
You need to lead a healthy lifestyle as well - night clubs and late nights won't help you put in a decent performance.
KEEP YOUR COOL
Temperament is also a major factor - and I think that applies to any sport.
The essence of sport is competition, and if you 'lose your rag' every time you don't get your way you will always let yourself down.
It doesn't matter how much ability you have, if people think you might let them down they won't want you in their team.
