Kelechi Iheanacho came on with seven minutes of the 90 remaining in the Scottish Cup semi-final, but it was in extra-time that the Nigerian internationalist made a massive impact on the match.

He netted twice to help the Hoops beat St Mirren 6-2 and book their place in next month’s final against Dunfermline Athletic.

The first was a near post header from a James Forrest cross and then he produced a stunning left-foot finish from inside the area.

The 29-year-old was delighted with his goals and the end result, as he explained to Celtic TV after the game.

“I can’t really describe how I feel at the moment,” Iheanacho said. “I’m really happy!

“Obviously, there was a little bit of panic in the second half when they got the goals.

‘We were lucky enough to get to extra-time and we blew them away after that.’

“We’re really happy as a team, we really worked hard in extra-time to get the goals.

“In extra-time, we just had to get after them, press them and get the goals, that was the plan.”
