Sources close to Blatter confirm the likely abolition of the game's most/only complicated rule - and most difficult to implement.
Defenders will be unable - when their team has the ball - to essentially reduce the pitch by 50% and, consequently, the game will become more open.
Linesmen (assistant referees) will be able to concentrate on goal lines, handballs, diving etc. The rule change may well make technology (advocated by many) unnecessary.
Green Cards MAY also be introduced (like hockey); this would signify an immediate 5 mins in the sin-bin and totally eradicate the constant moaning and arguing from players, unlike (say) rugby.
