Weekend four to watch

Here are four games to look out for in the SPFL this weekend:

Ross County v Celtic - Ladbrokes Premiership
Leaders Celtic have established a six-point advantage over closest challengers Hearts following their 3-1 home win over Aberdeen last weekend. Ronny Deila's men head to Dingwall for the Sunday game - live on BT Sport at 3.30pm - on the back of a Europa League tie with Molde. County have been generally strong at home, winning four of their six league matches.

St Mirren v Hibernian - Ladbrokes Championship
Hibernian are unbeaten in nine league games and journey to Paisley after back-to-back wins over Rangers and Dundee United at Easter Road. Saints find themselves eighth in the table and are yet to win at home in the Ladbrokes Championship but they earned a point in the capital earlier this season. Alex Miller, who has managed both teams, was this week appointed to work alongside Buddies boss Ian Murray.

Brechin City v Ayr United - Ladbrokes League 1
It's bottom against top at Glebe Park but Darren Dods' side will be boosted by last week's derby victory over Forfar Athletic at Station Park. City have lost four out of five at home while Ian McCall's men remain unbeaten in Ladbrokes League 1 since the opening day and hold a one-point lead over title rivals Dunfermline.

Elgin City v Annan Athletic - Ladbrokes League 2
Annan won 1-0 at East Fife last week, despite playing the second half with 10 men, to move five points clear at the top of the table. They will face another tough task against an Elgin side who made it four home wins out of five with a 2-0 victory over Arbroath on Saturday - a result that lifted Jim Weir's team back into the play-off places.
