IT will be an interesting half time team talk for Cliftonville manager Tommy Breslin as his team are two goals behind at home.
There has been a tremendous atmosphere at Solitude before a capacity crowd of 5,442 in north Belfast.
But Celtic have coped better under the bright Belfast evening sunlight.
Lustig put the visitors 1-0 nil up after 24 minutes with a fabulous goal which stunned Reds fans.
And six minutes later Georgios Samaras put The Hoops two up.
Ten minutes before half time Chris Commons thought he had score when he thumped a shot goal wards which struck the post and bounced away from the goal.
It will be an uphill task for Cliftonville in the second half to claw back two goals and stop Celtic scoring anymore.
