LA Galaxy star Beckham knows all about the FieldTurf surface as three MLS clubs count on the artificial pitch system.

"You can't play a game like soccer on that sort of field. What it does to your body as a soccer player, you're in bits for three days after that," said Beckham.

Former Liverpool favourite Steve Nicol, whose New England Revolution also use the surface, said: "There is no give in it. Grass is still the best surface."
