Should Celtic sell Moussa Dembele in January? Would £18m be a good price for the France Under-21 striker, or should they hold out for the £25m some reports suggest they want?

Hearts are reportedly ready to accept £300,000 for winger Jamie Walker from Wigan Athletic. Is that a good deal given the winger is out of contract this summer?

Rangers are said to want midfielder Andy Halliday back from Gabala - and forward Michael O'Halloran from St Johnstone. Would that be welcomed by fans at Ibrox?

Celtic have been linked with Dundee defender Jack Hendry.

Reports that Celtic are in talks with Brighton about a proposed transfer of Moussa Dembele to the English Premier League club dominate the Boxing Day newspaper headlines.

Suggestions that an £18m fee has been agreed have been described as "nonsense" by a Celtic source speaking to BBC Scotland, but we'll find out soon what manager Brendan Rodgers has to say.

He might also be tackled on a report saying defender Erik Sviatchenko is heading for Copenhagen.

Meanwhile, also in our round-up:

- Wigan Athletic are said to have opened talks with Hearts for winger Jamie Walker

- Rangers are said to be trying to bring back Andy Halliday from Gabala and Michael O'Halloran from St Johnstone

- Falkirk are reportedly on the verge of accepting an offer from Swansea City for defender Tony Gallacher that is less than the £750,000 they rejected last year

- And troubled Stranraer have apparently asked their players to accept a pay cut

Scottish Premiership (12:30)

Dundee v Celtic

Scottish Championship (14:00)

Dumbarton v Livingston

It's Boxing Day, but instead of the usual full card of Scottish fixtures, all eyes are on Dens Park - apart from those of supporters from Dumbarton and Livingston that is.

Scottish Premiership leaders Celtic visit Dundee in the early kick-off at 12:30, with the Championship game starting an hour and a half later.

We'll be concentrating on the build-up, commentary and aftermath of the match at Dens Park, with updates too from events beneath Dumbarton Rock.
