Fifa president Sepp Blatter has apologized to the Football Association over Frank Lampard's disallowed goal in England's World Cup defeat by Germany.

Blatter said the error had convinced him to reopen the debate on goal-line technology at a board meeting in July.

Lampard was denied a goal in Sunday's 4-1 second-round loss, even though his shot clearly crossed the line.

Blatter also said sorry to Mexico after Carlos Tevez's offside goal was allowed to stand in Argentina's 3-1 victory.

Lampard's strike came during a spell of England dominance and would have levelled the score at 2-2.

Blatter said the issue will now form part of the agenda at next month's meeting of the International FA Board, the body that decides the laws of the game.

"It is obvious that after the experiences so far at this World Cup it would be a nonsense not to reopen the file on goal-line technology," stated Blatter.

The Tevez goal - the first in Argentina's win on Sunday - was replayed on the screens in the stadium, sparking angry clashes between officials and the Mexican players and coaches.

"Personally I deplore it when you see evident referee mistakes but it's not the end of a competition or the end of football, this can happen," added Blatter.

"Yesterday I spoke to the two federations [England and Mexico] directly concerned by referees' mistakes.

"I have expressed to them apologies and I understand they are not happy and that people are criticising.

"We will naturally take on board the discussion on technology and have the first opportunity in July at the business meeting."
