A fourth substitute will be made available for FA Cup games which go into extra time in the quarter-finals, semi-finals or final during the 2016-17 season.
The English FA announced the change on Wednesday with the new method used for the first time to try and see if it helps teams combat fatigue during extra time periods.
Another change to the 2016-17 FA Cup is that there will be no replays in the quarterfinal stage, meaning the games will finish on the day with extra time and penalties to take place if required.
In a statement on the FA’s website the governing body of English soccer revealed the proposal is subject to IFAB approval but will be used to test the effectiveness of one extra sub.
The format was used in the Copa America Centenario this summer and FA chief executive Martin Glenn is intrigued to see how it works.
“With The Cup now adopting a straight knockout format from the quarter finals onwards, the introduction of a fourth substitute in extra time will bring extra intrigue and interest. Also, from a technical point of view, it will be interesting to see how managers use the chance to make an additional substitution in such high-profile games and the impact it has on the final result.
“Player welfare and being mindful of the number of games people play at the elite level has also been a consideration.”
This may spice plenty of extra time periods which usually peter out and become a warm of attrition with both teams unwilling to take risks and clinging on for penalty kicks.
Having an extra sub may help spark added energy to proceedings but with both teams having a sub, they may just cancel each other out. – NBC Sports
