Nigeria International Striker Kelechi Iheanacho Made History Against Arsenal by Being The Fourth Sub.

The Nigerian striker was introduced in extra-time at Wemble with new rules allowing managers to make another change from the quarter-final stage.

Manchester City made history in their FA Cup semi-final with Arsenal by bringing on a fourth substitute, with Kelechi Iheanacho the man introduced.

Man City have goal wrongly disallowed. 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.

Ayr United had previously become the first side in Britain to make such a change, in a Scottish Cup clash with Queen's Park in January.
