And under such specific conditions, synthetic grasses show great advantages. After a long period of development, artificial grass technology has become more mature. Many technical indicators are close to natural grasses, which can meet the technical requirements for professional football competition on the playing field surface.
In this context, in 2001 FIFA introduced the "FIFA recommendation" quality certification system. UEFA and the multinational football associations immediately responded and placed more and more international competitions on artificial grass grounds. At the 118th annual meeting of the FIFA Council held in London, United Kingdom on February 28, 2004, FIFA passed a resolution allowing artificial turf to be used in professional games.
