FULL-TIME Celtic 3-0 Dundee Unitedpublished at 16:55 Greenwich Mean Time 15 February
Celtic move 16 points clear at the top of the Premiership following a dominant home performance.
Two fantastic first-half finishes from Callum McGregor and Jota were followed up by a spectacular Adam Idah strike in the second 45.
Dundee United, who failed to threaten throughout against the league leaders, are now 50 without a win against Celtic in all competitions. They remain fourth despite the defeat.

Motherwell 0-3 Ross County
Calum Macdonald
BBC Scotland at Fir Park
A mass exodus at Fir Park as Ross County seal the points with a fantastic goal on the break.
It all comes from a Motherwell free-kick, the ball into the box is awful, County break and it ends with Connor Randall drilling home from 25 yards.
There's not many Motherwell fans left here, and those that remain are letting the players know exactly what they think of them.
Terrible from Motherwell, but what a day for Ross County, they're only two points off the top-six as things stand.

Kheredine Idessane
BBC Scotland at Dens Park
There are just minutes of added time to go and the Aberdeen fans are loud and proud at the moment. They like coming to Dens, where they've now won twice this season, as well as beating Dundee 4-1 at Pittodrie.
More importantly, though, they're closing in on their first win in 15 league matches - since that Pittodrie defeat of the Dee in early November. If they can hold on another minute or so, they'll be back up to third in the table.
GOAL Kilmarnock 3-1 St Johnstonepublished at 16:53 Greenwich Mean Time 15 February
Graham Carey
That's the best thing St Johnstone have done all day, but it's come too late.
Carey plays the ball to Adama Sidibeh, who has his back to goal. He lays it to Jonathan Svedberg, and he plays in Carey who has continued his run.
Free in the box, he lashes in from close range.

Celtic 3-0 Dundee United
Nearly a fourth for Celtic in stoppage-time.
Auston Trusty thrashes a close-range half-volley off the wrong side of the post as this one winds down.

Celtic 3-0 Dundee United
Adam Idah makes way to great applause following that incredible strike. Fellow Irish forward Johnny Kenny is on in his place.
Postpublished at 16:48 Greenwich Mean Time 15 February
Kilmarnock 3-0 St Johnstone
Liam Donnelly is coming on, alongside Innes Cameron and Matty Kennedy - who both return from injury.
Marley Watkins, Fraser Murray and Liam Polworth are off.
GOAL Motherwell 0-3 Ross Countypublished at 16:47 Greenwich Mean Time 15 February
Connor Randall
And that will seal all three points for County.
A superb strike from distance, dragged low back across goal beyond the fingertips of the outstretched Ellery Balcombe.
Motherwell were all over the shop there.

Motherwell 0-2 Ross County
Motherwell are on course to drop out of the top six for the first time since August.
Just four clear of the relegation play-off spot at this rate too.

Kilmarnock 3-0 St Johnstone
Kilmarnock scorer Bobby Wales is replaced to rapturous applause. His place is taken by Bruce Anderson.
A fourth goal for him would be a real Brucie Bonus...
GOAL Celtic 3-0 Dundee Unitedpublished at 16:42 Greenwich Mean Time 15 February
Adam Idah
What a strike. Wow!
Adam Idah wraps his foot around the ball and thrashes it into the top corner from the edge of the box.
Simply stunning.
Postpublished at 16:41 Greenwich Mean Time 15 February
Celtic 2-0 Dundee United
It has taken over 20 minutes but we have finally been treated to another shot at Celtic Park.
United winger Glenn Middleton was the man taking aim, with his unassuming bouncing shot held with relative ease by Celtic number one Kasper Schmeichel.
CLOSE!published at 16:41 Greenwich Mean Time 15 February
Dundee 1-2 Aberdeen
Chaos erupts in the Aberdeen box as Dundee, not for the first time, split the visitors open with their speed on the break.
Seb Palmer-Houlden is prominently involved along with fellow replacement Finlay Robertson as shots pepper the away goalmouth. Aberdeen scramble it clear, by hook or by crook.
There's a quick VAR check for a possible handball, but play continues.
Arfield boosts Bairnspublished at 16:40 Greenwich Mean Time 15 February
Falkirk 2-2 Ayr United
Scott Arfield has scored four goals in two games since returning to Falkirk and, as things stand, the Bairns are staying top of the table.

YELLOW CARDpublished at 16:37 Greenwich Mean Time 15 February
Motherwell 0-2 Ross County
Ross County's Noah Chilvers picks up the first yellow card of the game as he lunges in at Callum Slattery.
Motherwell are awarded a free-kick around 25 yards out, that's fizzed narrowly over the bar by Slattery.
Motherwell are down but by no means out of this one yet.
YELLOW CARDpublished at 16:36 Greenwich Mean Time 15 February
Celtic 2-0 Dundee United

Emmanuel Adegboyega becomes the third United man to enter the referee's book after brazenly flinging Daizen Maeda to the deck.
English centre-forward Louis Moult is now on for the visitors, replacing Sam Dalby.
There has been nothing to report from Celtic Park - other than substitutions and bookings - since the hour mark.
GREAT SAVE!published at 16:34 Greenwich Mean Time 15 February
Dundee 1-2 Aberdeen
Fantastic stop from Jon McCracken to keep Dundee alive.
A curling free-kick from Ante Palaversa is powered goalwards by the head of Kristers Tobers, but the Dundee stopper leaps to his left and beats the ball clear.
CLOSE!published at 16:34 Greenwich Mean Time 15 February
Dundee 1-2 Aberdeen
An enticing opportunity wasted by Dundee, who are pressing for a leveller.
Seb Palmer-Houlden canters downfield on the break after an Aberdeen corner is dealt with. He has Simon Murray unmarked to his right, but opts to take on the shot - a shot so wayward it nearly ends up as a pass to his captain.
A frenetic game still hangs in the balance.
Hale on a hat-trickpublished at 16:34 Greenwich Mean Time 15 February
Motherwell 0-2 Ross County
Ronan Hale is enjoying his day out at Fir Park with two goals so far for Ross County and, as things stand, they are going eight points clear of bottom side St Johnstone in the Scottish Premiership.
