After soccer's latest high-profile goal-line controversy, FIFA President Sepp Blatter says using technology to determine whether the ball has crossed the line is a "necessity."

Ukraine was denied what appeared to be a legitimate equalizer in its must-win match against England at the European Championship because the official beside the goal couldn't see if the ball crossed the line before it was cleared away. Ukraine lost the match 1-0 and was eliminated.

Blatter says on Twitter that "After last night's match GLT is no longer an alternative but a necessity."

FIFA will decide on July 5 whether to approve either of the two goal-line technology systems being tested in England and Denmark.
