Celtic went eight points clear of Rangers at the top of the Ladbrokes Premiership with a 4-1 win over Motherwell at Parkhead.

But five players weighed in with goals in a 5-0 thrashing of Hamilton as Morelos completed his ban – including Kyle Lafferty, who netted his first league goal in five months.
