What are the key questions in Saturday's Scottish Premiership games?

Hibernian navigate major turmoil ahead of meeting Aberdeen following the dismissal of head coach David Gray, whose twelve-year association with Easter Road ended after Tuesday's loss against Kilmarnock. Caretaker boss John Potter must rally a squad enduring three consecutive Premiership defeats while attempting to halt a six-game home league losing skid that began last season.

They face an Aberdeen side reinvigorated under Stephen Robinson, who followed a cup shootout triumph over Killie by snapping a four-game scoreless, winless league drought with a 4-0 rout of Motherwell at Fir Park. Aided by Moroccan attacker Ayoub Mouloua, whose flair produced an eye-catching goal in midweek, the Dons can leap to fourth position with another victory.

Meanwhile, Kilmarnock host Heart of Midlothian after snapping their own poor run with a 1-0 success at Easter Road, marking their first league triumph this campaign following an opening stretch that yielded a solitary point from five outings. Manager Neil McCann praised the defensive resilience that halted a leaky start of 14 conceded goals as Killie aim to move off the foot of the standings.

They welcome a Hearts squad reeling from an unexpected setback against Falkirk that halted a nine-game unbeaten stretch. Hearts boss Wouter Vrancken expressed sharp frustration over his team's ball possession and offensive decision-making, particularly as the Tynecastle club travel to Ayrshire carrying a record of only two victories across their prior ten Premiership away fixtures, both occurring in Edinburgh derbies.
