They say it takes around 10,000 hours of training to become a professional athlete.
Such commitment has proven too much for many, as endless slogs on soggy training pitches drain all but the most keen, or foolhardy, competitors.
But now you can forget about countless months toiling away in the harsh winters of northern Europe, and get indoors to use the latest revolutionary robot training device, the 'Footbonaut'. Providing you have the finances to do so, of course.
This training aid is set to become the must-have gadget for professional teams - it's already being used by Bundesliga champions Borussia Dortmund.
The German giants have conquered all comers in the Champions League this season, beating the likes of Manchester City and taking points off Real Madrid.
These two big-spending giants of European football found their expensive squads of hired talent outworked, and outplayed, by Dortmund's young collection of attacking upstarts. Few underestimated Dortmund going into the Champions League, they are double Bundesliga champions after akk, but few can say they predicted such performances. Just how did they get so good?
Part of the secret lies in their revolutionary training device. 'The Footbonaut' aims to create a team of Iniesta's, focusing on first-touch, technique, awareness and speed of thought. Adidas have their own minature version based in their headquarters in Germany, and recently opened their doors to Jamie Redknapp for a road test.
Anyway here's how it works.
Dortmund's version uses a automatic ball-feeding machine placed into a 14 metre square area. The player, Gotze, Gundogan or Lewandowski, takes his place in the centre circle and the ball is randomly fired into the box at a variety of heights and angles, and at various speeds.
The participant then must take a touch, look up, and identify one of 64 targets within the cube. One of the 64 goals will light up, and the player must hit the target in the quickest time, before getting back into position to receive the next pass.
Whether you shank it sideways or hit the jackpot, all the data will be transmitted back to your coach's tablet computer.
It sounds like tough work, and GMF has got it's hands on a sneak peak video so you can check it out.
Have a watch here...
