France won Euro 2000 with a golden goal
We think the silver goal gives the best sporting chance to both sides
Uefa will introduce the "silver goal" ruling across European football's major tournaments, including this season's Uefa Cup and Champions League final.
It replaces the "golden goal" method of deciding matches in extra time.
The "golden goal" system gives the team which scores first in extra-time the victory no matter how much time has elapsed.
But the "silver goal" method will allow the side who have conceded the goal a chance to play on until the end of that particular half.
"It will be an innovation at this year's finals, first at the Uefa Cup final in Seville, then in Manchester for the Champions League final," said Uefa spokesman Mike Lee.
"After that, we will use it to decide all our matches where it's needed in all our competitions.
"At the moment there are many models in use throughout the world to decide finals.
"But we think this gives the best sporting chance to both sides and we hope that in time this innovation could be used throughout the world as the standard way of deciding matches."
Teams who have benefited from the "golden goal" in previous big finals include Germany at Euro 96, France at Euro 2000 and Liverpool's 2001 Uefa Cup success over CD Alaves.
