BBC Scotland's chief sports writer on SportsoundAberdeen have shown incredible skill and guts. Celtic must have thought they had won this several times.
I can't think of a better cup tie I've seen.

James McFadden
Former Scotland forward on BBC One ScotlandIt is a brilliant cross in, begging to be headed at the back post.
It's similar to the goal that gets Aberdeen out of regulation time.
Hoilett, what a delivery that is. Celtic are all over the place defensively.

Kheredine Idessane
BBC Scotland at HampdenAll the Aberdeen players went down to celebrate with their fans when yet another late equaliser added to the drama here at Hampden. What. A Match.
Their interim boss, Peter Leven, did a little jig of delight down the touchline. You can hardly blame him. Celtic counterpart Brendan Rodgers couldn't believe what he'd just seen.

Angus MacDonald
Oh my, oh my!
Junior Hoilett's deep cross finds the head of Angus MacDonald to head down and past goalkeeper Joe Hart.
The stand-in captain has certainly made up for his early mistake for Celtic's opener.

Great chance for Celtic to settle it.
Matt O'Riley squares for the unmarked Adam Idah, but it is a bit behind the striker, who makes a mess of his shot in front of goal.

Somehow Celtic survive again.
Having scored Aberdeen's second, Ester Sokler pounces on a header into the six-yard box.
The striker prods wide under pressure, but it might have been offside in any case.

It looked like Don Robertson has pointed to the penalty spot.
Cameron Carter-Vickers kicks the heel of Junior Hoilett inside the penalty box.
However, after a VAR check, it somehow ends up as a free-kick to Celtic.
