Jonathan Sutherland presents highlights from the fourth round of the Scottish Cup.

This is one of the most exciting days in the Scottish football calendar as teams from the lower leagues aim to make history against more illustrious opponents.

Championship side Brechin City travel south to face Celtic, current holders of all three Scottish football trophies and unbeaten in domestic cup competition since a Scottish Cup semi-final loss in April 2016.

Elsewhere, there are two all-Premierships ties, including a Lanarkshire derby. Motherwell at home look to avenge a 3-1 defeat at Hamilton just before the winter break, while Ross County travel south from Dingwall to take on Steve Clarke's rejuvenated Kilmarnock side. 2014 Scottish Cup winners St Johnstone travel to League One Albion Rovers and Premiership side Partick Thistle face a tricky trip to Dumfries to face Championship outfit Queen of the South.

Plus the best moments from Friday night's Highland League derby as Fortmartine welcome Aberdeenshire rivals Cove Rangers to Pitmedden.

With all the goals from around the country and expert comment and analysis on all the key games.
