Celtic took the first step towards the Champions League with a comfortable 2-0 win over part-time Linfield at Windsor Park.
However the Belfast game sparked controversy when striker Leigh Griffiths received a booking after being repeatedly struck with objects from the stands.
Among the missiles thrown at him was a bottle of Buckfast.

However, there were around 300 Hoops fans in the Kop stand, set aside for them in a half-full stadium, to see attacker Scott Sinclair head Brendan Rodgers’ side ahead in the 17th minute before midfielder Tom Rogic made it 2-0 five minutes later.
