Adam Idah was off like a rocket, Callum McGregor was warning his team-mates to stay focused and even a steward was jumping with joy at Celtic's last-minute winner against Rangers.

For Matt O'Riley, though, it was a display of emotion after Idah fired past Jack Butland.

The central midfielder showed his delight at the match-winning finish as he stood alone in the box and shouted to the skies.

O'Riley, 23, let it all out in the penalty box and he relished the moment at Hampden.

As Idah blasted under Butland, O'Riley glanced to the linesman to be sure of no offside before thrusting his arms out with vigour in celebration.

The midfielder erupted with emotion after the strike before later linking up with his team-mates celebrating in the opposite corner.

On X, formerly Twitter, Martin Donaldson shared a clip of the special moment as he highlighted O'Riley's solo celebration.

He posted: "Matt O'Riley celebrating the winner is superb.

"Standing in the 18yard box, checks the linesman & just let's it all out - magic."

It comes as speculation mounts over serious transfer interest in O'Riley in the summer transfer window.

An Atletico Madrid approach was booted out in January but Celtic are thought to be braced for bids with Premier League clubs and Serie A side Inter Milan reportedly interested.

On talks of a transfer exit, O'Riley said last week: "That's a tough question. 

"It would be very difficult[to leave Celtic]. I have said before, the club means a lot to me now.

"Right from day one I kind of fell in love with the club because the fans are so crazy and passionate - it is just a proper fan base.

"One more game to focus on and then take it from there."
