Celtic complete unbeaten domestic treble
Aberdeen's 27-year wait for Scottish Cup continues
Celtic win the Scottish Cup for the 37th time to seal an unbeaten domestic treble. What an achievement from Brendan Rodgers' side but you have to feel for Aberdeen, who put so much into a hugely entertaining game.
Celtic 1-1 Aberdeen
Patrick Roberts is off as Celtic eat up a few seconds and beef up their defence with the arrival of Erik Sviatchenko.
Scott Wright is on for the Dons, with Ryan Jack making way in the final seconds.

Quote MessageThe Aberdeen players are heartbroken, they are on their knees. They have put so much into this game.
Tom Rogic
Have Celtic just sealed an unbeaten treble in injury time? It looks very like it as Tom Rogic glides past Anthony O'Connor and an exhausted Andrew Considine before rifling an angled shot past Joe Lewis at the keeper's near post.

We'll get three additional minutes as Celtic force a corner. Leigh Griffiths' delivery curls straight out of play and the big defenders who have come up from the back will need to trudge all the way back.

Do we have time for a dramatic late winner or are we going into extra time?
Scott Sinclair pops up in the Aberdeen penatly area again but can only scoop an awkward shot high and wide.

With the rain still lashing down, Leigh Griffiths pings an excellent free-kick to the back post where a sliding Mikael Lustig somehow heads the ball away from goal. Another good chance spurned by Celtic as the clock runs down.

Jonny Hayes has a word with the Aberdeen management team. It looks like he's struggling a bit. Will he be able to continue?

Quote MessageThis now has the feel of two heavyweights slugging it out in the final stages of a prize fight. Both teams defending desperately and breaking with purpose when they get the chance. Something has to give.

Quote MessageScott Sinclair has missed two absolute sitters. It's as if the ball gets stuck under his foot as he goes to half-volley it into the net.
Celtic 1-1 Aberdeen
Scott Sinclair fluffs his lines inside the six yard box again. The Celtic forward is all alone at the back post but mis-hits his volley, allowing Joe Lewis to block.
Aberdeen are under the cosh now...
Celtic 1-1 Aberdeen
Tom Rogic slides a lovely pass through for Leigh Griffiths to run on to. The Celtic striker steadies himself near the edge of the box and fires off a firm, low strike but he can't get past Joe Lewis, who gets a strong hand to it.
Celtic 1-1 Aberdeen
Another change for the Dons as Niall McGinn is replaced by Anthony O'Connor.
Will that be McGinn's last contribution for the Dons? He looks sure to be moving on under freedom of contract in the summer.
Celtic 1-1 Aberdeen
Aberdeen have found a second wind here, with Graeme Shinnie covering an unnatural amount of ground. The Dons skipper has a crack from distance, catching the shot sweetly, and Craig Gordon is at full-stretch to push it away.
Celtic 1-1 Aberdeen
It's end to end stuff now as Adam Rooney finds space on the right but the Aberdeen substitute is not quick enough to escape the younger legs of Callum McGregor.

Quote MessageCeltic are creating the better opportunities. Boyata escapes his marker and really must score. He's got to hit the target at least.
Celtic 1-1 Aberdeen
Patrick Roberts is seeing more of the ball now as he glides past a couple of opponents and stands up a good cross. Ash Taylor needs to make a clever clearing header over his own crossbar, with Scott Sinclair lurking.
From the corner, Dedryk Boyata gets a powerful connection on his header but cannot steer it on target. He has to be doing better there.
Celtic 1-1 Aberdeen
The rain is back but it is certainly not dampening the enthusiasm of the crowd, with both sets of supporters really cranking up the noise.
Celtic 1-1 Aberdeen
Are Aberdeen's energy levels dipping? The Dons are in trouble from a corner and relieved to see Mikael Lustig stabbed shot trundle wide.
Celtic 1-1 Aberdeen
That's more like it from Patrick Roberts as he cuts in from the left, twisting his way past Mark Reynolds before taking aim for the far corner. Joe Lewis gets a fingertip to it, taking the ball onto the post. Fantastic save from the big man.
