On-loan Manchester United striker James Wilson comes on for Sam Cosgrove.

Bit of a thankless task for the young man.

Jozo Simunovic must wonder what he has to do to score for Celtic today.

The big centre-half, who came close twice early on, meets a Mikael Lustig cross superbly on the volley, but it flies just wide of a post.

It is like a training exercise now for Celtic against Aberdeen's nine men.

Celtic are peppering the Aberdeen goal with shot after shot and, after a couple of simple saves by Joe Lewis, a Scott Sinclair drive is deflected wide.

Celtic manager Neil Lennon gives big hugs to Jonny Hayes and James Forrest as the wingers are replaced with Timothy Weah and Scott Sinclair.

Aberdeen manager Derek McInnes joins his assistant, Tony Docherty, in the stand after apparently having said something to the fourth official.

It is almost four as Jonny Hayes unleashes a drive that forces goalkeeper Joe Lewis to tip the ball over the crossbar.

Aberdeen manager Derek McInnes responds by replacing Greg Stewart with midfielder Stephen Gleeson.

But it is all about damage limitation now as thousands of Aberdeen fans stream out of Hampden.

A rash challenge from Lewis Ferguson, going in two-footed on Tom Rogic leads to an inevitable second red card for Aberdeen.

What was the 19-year-old midfielder thinking? The Dons have lost their heads.

Max Lowe is the next Aberdeen player to go into the book, the on-loan Derby left-back being penalised for a rash challenge.

Michael Devlin pushes Jonny Hayes on the back and the former Aberdeen man wins a penalty.

What was the central defender thinking. He hesitated going for a cross lofted deep into the penalty box and allowed the ball to fall at the winger's feet.

The ghost of Graeme Shinnie is haunting Aberdeen.

Celtic are exploiting the wide open spaces down the centre of the park usually so well patrolled by the suspended captain.

Even centre-backs Jozo Simunovic and Kristoffer Ajer are taking advantage and strolling deep into the opposition half.

Aberdeen will take heart from the fact that Rangers came from behind to equalise against Celtic when down to 10 men recently - even if they eventually lost the game.

Shortly after the break, they did manage to reach the Celtic penalty box, but they squandered a couple of chances to deliver a good cross, with Max Lowe slipping comically at the end of it all.

That just about summed up Aberdeen's afternoon so far.

Andrew Considine is next in the book with a tug on the shirt of Celtic striker Odsonne Edouard on the edge of the Dons penalty box.

So close to a second goal for Celtic as Callum McGregor thrusts into the penalty box and his low cross-come-cross is back-heeled off the line by Max Lowe before being cleared.
