Kelechi Iheanacho’s introduction in Manchester City’s FA Cup semi-final clash against Arsenal, meant that he became the first player to be brought on as a fourth substitute in the competition.

New rules for the 2016/2017 season, allow managers to make one more extra change if the game goes into extra time, even if they have already made three previous substitutions.

The law came into effect from the quarter-final stage of this season’s competition, but was not put into practice until a last-four encounter at Wembley.

Pep Guardiola had already brought on Raheem Sterling, Fabian Delph and Fernando into the match. But when his side went behind to an Alexis Sanchez goal, the Spaniard called on Iheanacho, with the hope of finding a late equalizer.

The move did not pay off, as City came up short against the Gunners.
