• Celtic stroll to 4-0 win over Motherwell while rivals slip
• Aberdeen hammered at Kilmarnock as slump goes on

Celtic stretched their lead at the top of the Scottish Premiership to 12 points after their 4-0 Boxing Day win over Motherwell was followed by Rangers slumping to a 2-1 evening defeat at St Mirren that left their manager, Philippe Clement, lamenting their "below par" mentality.

Earlier, Brendan Rodgers's side had eased to a comfortable victory over Motherwell after getting a penalty breakthrough in first-half stoppage-time. Arne Engels opened the scoring after a tight first half as Aston Oxborough, the Motherwell goalkeeper, was penalised for a collision with Yang Hyun-jun. Daizen Maeda doubled the lead before the substitutes Nicolas Kühn and Reo Hatate struck to give Stuart Kettlewell, the visiting manager, a first taste of defeat in four visits to Celtic Park.
